I have an old toshiba satellite a205 which has a fan that turns on at 50 degrees and turns off at 45 degrees. It's a much too narrow range, so the fan is starting up every two minutes or so -- having it turn off at 40 degrees would probably make more sense. To this effect I wanted to see if I could get apci fan support.
In the end I don't seem to have succeeded, but here's what I did manage to do, and what happened:
Go:
Install build-essential and the kernel headers for your kernel
git clone git://omnibook.git.sourceforge.net/gitroot/omnibook/omnibook
cd omnibook/
vim polling.c
comment out lines 128:
// cancel_rearming_delayed_workqueue(omnibook_wq, &omnibook_poll_work);
and 191 using // :
// cancel_rearming_delayed_workqueue(omnibook_wq, &omnibook_poll_work);
Run:
sudo make load
sudo make load
Read through doc/INSTALL, then
WARNING:
Some say that loading with the wrong ectype can be bad for you computer. My guess is that things will be fine as long as you don't put the computer on heavy load while trying the method below out so that you don't risk burning anything.

OK, time to try the shotgun approach:
var=1 && sudo rmmod omnibook && sudo modprobe omnibook ectype=$var && ls /proc/omnibook
Do this with values of var from 1-16. See which one gives the 'best' support. For me most things showed up for all ectypes between 1 and 10, but only ectype=1 show fan_policy
Next do cat /proc/omnibook/fan , cat /proc/omnibook/display, cat /proc/omnibook/battery etc. to see whether the settings seem to correspond to reality.
ectypes
I can't find the original document which details the different ectypes and the corresponding laptop models. Your best guess is to do like I did above (just trying randomly) or to google for omnibook and ectype and see which model is closer to yours.

Making omnibook load on boot:
vim /etc/modules
add a line saying
omnibook
and the create a file called omnibook.conf under /etc/modprobe.d
In /etc/modprobe.d/omnibook.conf you put a single line:
options modprobe ectype=12
cat /proc/omnibook/fan_policy gives
Fan off temperature: 0 C
Fan on temperature: 0 C
Fan level 2 temperature: 0 C
Fan level 3 temperature: 0 C
Fan level 4 temperature: 0 C
Fan level 5 temperature: 0 C
Fan level 6 temperature: 10 C
Fan level 7 temperature: 108 C
Minimal temperature to set: 25 C
Maximal temperature to set: 95 C
