I think the fan is correctly managed, as you can see from my attached:
=====
luca@gismo:~$ cat /proc/acpi/thermal_zone/THRM/temperature
temperature:             68 C
luca@gismo:~$ date
Sun Nov  2 20:50:06 CET 2003
luca@gismo:~$ cat /proc/acpi/thermal_zone/THRM/temperature
temperature:             55 C
luca@gismo:~$ date
Sun Nov  2 20:52:44 CET 2003
luca@gismo:~$ cat /proc/acpi/fan/FN00/state
status:                  on
luca@gismo:~$ cat /proc/acpi/fan/FN00/state
status:                  off
luca@gismo:~$
=====

The temperature went high compiling the kernel, but suddenly the fan 
went on and at high RPM (I could hear it), just for 5min and then it 
went normal again.

I have always the 'os_wait_semaphore' problem, but, as Karol said in 
another post, this doens't cause any big problems, just the already 
reported keyboard bug (for less than 5min you can't type anything or if 
you were typing sometimes it's as if you go on typing the last character).

Thx, bye,
Gismo / Luca
