There is no way to get the temperature using nouveau at the moment. This 
feature should land in nouveau git some time this week.

Reading the temperature is not as straightforward as just reading a 
register. It works that way on nv84+, for earlier cards, you need to 
parse the vbios to set-up the sensor and then read the temperature (and 
change the value with some additional little calcultations). The 
documentation should be available soon, I'm working on merging all the 
doc we have.
