(SOLVED)ACPI freezes system when certain temperature reached

I have an Acer Travelmate 4002, and I'm using kernel 2.6.21.
Lately, my computer keeped freezing - full freeze, no mouse, no keyboard, hard reboot needed - while updating.
After some experimentation, I have found out the feezes always happen when the THRM sensor reaches 65ºC.
At first, I thought it was a hardware problem, but some tests on Windows seem to contradict this (Windows works at 70ºC no worries).
If I launch a compilation from the first console, no X running, I can see, instead of a complete freeze, what seems to be an infinite ACPI log scrolling. Unfortunately, it's so fast I can't read it (but the header of the lines, which is [ACPI] I think).

I've been googleing around but I can't find anything. I don't even know where to start looking. The acpid logs don't show anything.
¿Any suggestions?

Throttle down the processor. My computer is similar. When it hits 65C on the processor the fan turns on and temporarily locks the system. It does come back, but it does this about every second. I always just throttle my 3Ghz processor down to 2.25, and it never overheats,

EDIT: AFAIK, that "feature" is in bios and cannot simply be turned off by any means.

I fear this would work. I already tried throttling it down from 1.6GHz to 600MHz to no avail.
Furthermore, the freezes didn't happen two weeks ago, and still don't under Windows, so I know it must be something software-side in my current Linux conf, but I really don't know what can have changed or where to look.

I have updated the kernel to version 2.6.22 and the problem seems to have vanished.
