nouveau shuts the machine down with v3.9-rc1 (temperature (72 C) hit the 'shutdown' threshold).

[Martin Peres]

Hi everyone,

As a follow up, Konrad sent me in private his vbios and the issue turned 
out to be trivial.
The reason why it behaved this way was that his vbios didn't have sensor 
calibration values.
The fix is available here: 
http://gitorious.org/linux-nouveau-pm/linux-nouveau-pm/commit/59b4006b5b30828bbd094dffe3937333b43d1e12

This fix is part of a pull request I sent to Ben.

Thanks again Konrad for reporting and testing the patches, I'll add you 
as a tester to this patch :)

Cheers,
Mupuf
