You can check the temperature by running nvidia-settings. If you can't
see the temperature in it, then nvidia doesn't support it on your card and
I'm not sure we should :s

Thanks for the vbios you sent me in private. For the others, the reason
why he doesn't have temperature anymore is because his vbios lacks
sensor calibration values.
