Toshiba satellite L505, Hdry H20 BIOS, intell dual core CPU

Also seeing same issue as above.

(1) Default fan behavior is it will not come on unless I open the ubuntu
software center , then it comes on full blast and will not turn off.
Monitoring temperature is impossible.

(2) doing "sudo apt-get install acpi" allows temperature of CPUs to be
checked from command line, but fan will not come on no matter what after
that is installed. I just get to watch my processor temp creep up until
I panic around 70 C and restart with Windows 7 so the fan will come on
and cool it down.

(3) adding acpi_osi="Linux" to /boot/grub/menu.lst on the appropriate
line (coresponding to the kernel I boot) AND haveing acpi installed will
start the fan on some low speed at cold boot, and it will stay on
continuously at that speed. However, the fan will turn off upon
hibernation, and not turn back on again after that unless the laptop is
restarted.

#3 seems to be best senario, but not adequate for CPU-intense activities

-Would love more information on the proprietary ATI bit by Anakin StarKiller.  
Any chance you could provide a brief description somewhere for a new linux user 
to follow?
