Hallo Andrew,
I have a little problem getting my cpu fan to work proppably 
with linux.
The ACPI module you coded creates a file in the proc fa calle 
"trip_points".
When I cat this file I get the following:
cat trip_points
critical (S5):           85 C
passive:                 95 C: tc1=2 tc2=5 tsp=300 devices=0xc12c7680

So my fan is running the hole time (sometimes slower, 
sometimes faster, but 
never realy stops). btw. I have a Acer 613TXC Notebook with 
Phoenix BIOS 
(latest version).

You will notice that your system does not have an "active" entry. This
generally means that the fan is not under ACPI's control. So, the OS
power policy can read the temp (what does your temperature read?) and
implement passive cooling (throttle the CPU) and may shut the system
down when the temp hits 85C (wow, pretty hot) but it doesn't know about
any active cooling mechanisms.

passive at 95 and critical at 85 ?!  Oh my..
