OK, I have done further investigation on this and got some information from the
manufacturer about the Windows battery utility:

This led me on a merry chase through lm-sensors land, where I found that the
"sensors-detect" program reports:

Driver 'smartbatt' (should be inserted)
  Detects correctly:
  * Bus 'CS5536 ACB0'
    Busdriver `UNKNOWN', I2C address 0x0b
    Chip `Smart Battery' (confidence: 5)

OK, that looks pretty good so far.  But I try to track down the smart battery
driver and find that it is no longer in I2C, but is back in ACPI!  

I have enabled the 'Smart Battery' driver in ACPI but still no battery
reported.

Any ideas? 

Thanks,
Bill Gribble
