So perhaps its good time to create Documentation/acpi? ;-).

Anyway it is not *dangerous* situation. ACPI machines power down on
overtemp.
Pavel,
who forced his toshiba satellite to 95Celsius CPU temp to see how it
behaves, and who has hp omnibook xe3 with broken cpu fan and 900mhz
athlon. Yes I have seen emergency shutdowns many time already.

[BTW toshiba is designed properly, and even without fan is able to
passively cool itself by going from 300MHz to 40Mhz. Omnibook is
broken and its thermal throttling is not capable of keeping CPU cool
enough. What is worse, in some cases omnibook cpu makes harddisk hot
(while cpu is in limit and machine does not do emergency poweroff),
leading to bad things (tm).]
