92C while compiling for more than 5-10 minutes, is normal. It is NOT normal
that the system goes there for no reason or if it is ever actually over 60C

It is, 915 or 855PM chipsets control this stuff a lot, so as other Pentium
processors, which was not a feature of older AMD processors. :/ (/me recalls
the Tom hardware video)

It is handled by BIOS-Chipset.

It can, you can make a daemon to look at the Temperature and halt if temp >
90C

Crash look means the System turned off itself. It is recomended to not turn
it OFF, but stay in a boot screen or so...

IT does not make dramatic changes for Power Management. Else, it would be
flying like crazy.

Yes, we need to get this feature working ASAP.
