Hello. I've recently had some problems with my sensor chips, got to #linux-sensors on freenode, and got to send you the following:

My motherboard is DG33FB, arch is x86_64 on gentoo, kernel - 2.6.22-gentoo-r5, vanilla-sources. The problem with sensor chips is that the info may only be available through SMBus only (ISA disabled), but for now I can only access ISA. I hope this one may be useful too:
  1. # sensors-detect revision 4930 (2007-10-09 13:32:39 +0200)
  2.  
  3. This program will help you determine which kernel modules you need
  4. to load to use lm_sensors most effectively. It is generally safe
  5. and recommended to accept the default answers to all questions,
  6. unless you know what you're doing.
  7.  
  8. We can start with probing for (PCI) I2C or SMBus adapters.
  9. Do you want to probe now? (YES/no):
  10. Probing for PCI bus adapters...
  11. Use driver `i2c-i801' for device 0000:00:1f.3: Intel ICH9
  12.  
  13. We will now try to load each adapter module in turn.
  14. Module `i2c-i801' already loaded.
  15. If you have undetectable or unsupported adapters, you can have them
  16. scanned by manually loading the modules before running this script.
  17.  
  18. To continue, we need module `i2c-dev' to be loaded.
  19. Do you want to load `i2c-dev' now? (YES/no):
  20. Module loaded successfully.
  21.  
  22. We are now going to do the I2C/SMBus adapter probings. Some chips may
  23. be double detected; we choose the one with the highest confidence
  24. value in that case.
  25. If you found that the adapter hung after probing a certain address,
  26. you can specify that address to remain unprobed.
  27.  
  28. Next adapter: SMBus I801 adapter at 4000 (i2c-0)
  29. Do you want to scan it? (YES/no/selectively):
  30. Client found at address 0x44
  31. Probing for `Maxim MAX6633/MAX6634/MAX6635'...              No
  32. Client found at address 0x50
  33. Probing for `Analog Devices ADM1033'...                     No
  34. Probing for `Analog Devices ADM1034'...                     No
  35. Probing for `SPD EEPROM'...                                 Yes
  36.     (confidence 8, not a hardware monitoring chip)
  37. Probing for `EDID EEPROM'...                                No
  38. Client found at address 0x52
  39. Probing for `Analog Devices ADM1033'...                     No
  40. Probing for `Analog Devices ADM1034'...                     No
  41. Probing for `SPD EEPROM'...                                 Yes
  42.     (confidence 8, not a hardware monitoring chip)
  43. Probing for `EDID EEPROM'...                                No
  44.  
  45. Next adapter: NVIDIA i2c adapter  (i2c-1)
  46. Do you want to scan it? (YES/no/selectively):
  47. Client found at address 0x50
  48. Probing for `Analog Devices ADM1033'...                     No
  49. Probing for `Analog Devices ADM1034'...                     No
  50. Probing for `SPD EEPROM'...                                 No
  51. Probing for `EDID EEPROM'...                                Yes
  52.     (confidence 8, not a hardware monitoring chip)
  53.  
  54. Next adapter: NVIDIA i2c adapter  (i2c-2)
  55. Do you want to scan it? (YES/no/selectively):
  56.  
  57. Next adapter: NVIDIA i2c adapter  (i2c-3)
  58. Do you want to scan it? (YES/no/selectively):
  59.  
  60. Some chips are also accessible through the ISA I/O ports. We have to
  61. write to arbitrary I/O ports to probe them. This is usually safe though.
  62. Yes, you do have ISA I/O ports even if you do not have any ISA slots!
  63. Do you want to scan the ISA I/O ports? (YES/no):
  64. Probing for `National Semiconductor LM78' at 0x290...       No
  65. Probing for `National Semiconductor LM78-J' at 0x290...     No
  66. Probing for `National Semiconductor LM79' at 0x290...       No
  67. Probing for `Winbond W83781D' at 0x290...                   No
  68. Probing for `Winbond W83782D' at 0x290...                   No
  69. Probing for `Silicon Integrated Systems SIS5595'...         No
  70. Probing for `VIA VT82C686 Integrated Sensors'...            No
  71. Probing for `VIA VT8231 Integrated Sensors'...              No
  72. Probing for `IPMI BMC KCS' at 0xca0...                      No
  73. Probing for `IPMI BMC SMIC' at 0xca8...                     No
  74.  
  75. Some Super I/O chips may also contain sensors. We have to write to
  76. standard I/O ports to probe them. This is usually safe.
  77. Do you want to scan for Super I/O sensors? (YES/no):
  78. Probing for Super-I/O at 0x2e/0x2f
  79. Trying family `National Semiconductor'...                   Yes
  80. Found `Nat. Semi. PC8374L Super IO Sensors'                
  81.     (but not activated)
  82. Probing for Super-I/O at 0x4e/0x4f
  83. Trying family `National Semiconductor'...                   No
  84. Trying family `SMSC'...                                     No
  85. Trying family `VIA/Winbond/Fintek'...                       No
  86. Trying family `ITE'...                                      No
  87.  
  88. Some CPUs or memory controllers may also contain embedded sensors.
  89. Do you want to scan for them? (YES/no):
  90. AMD K8 thermal sensors...                                   No
  91. AMD K10 thermal sensors...                                  No
  92. Intel Core family thermal sensor...                         Success!
  93.     (driver `coretemp')
  94. Intel AMB FB-DIMM thermal sensor...                         No
  95.  
  96. Now follows a summary of the probes I have just done.
  97. Just press ENTER to continue:
  98.  
  99. Driver `coretemp' (should be inserted):
  100.   Detects correctly:
  101.   * Chip `Intel Core family thermal sensor' (confidence: 9)
  102.  
  103. I will now generate the commands needed to load the required modules.
  104. Just press ENTER to continue:
  105.  
  106. To load everything that is needed, add this to some /etc/rc* file:
  107.  
  108. #----cut here----
  109. # Chip drivers
  110. modprobe coretemp
  111. # sleep 2 # optional
  112. /usr/local/bin/sensors -s # recommended
  113. #----cut here----
According to the docs, my chipset uses the National Semiconductor PC8374L IC.
