I did and saw the list you generated for the T61 which is what I have. 
I'm wondering if one of those other 3 unknown devices might be the GPU. 
  I suppose the GPU might not have a sensor and that I could rely on the 
main temp as an indicator.

I was having some overheating issues on this T61 running Karmic Alpha 3 
thanks to a Metacity bug causing CPU pegging.  I was hoping to monitor 
the GPU directly because over time I would experience some video 
degradation with the CPU pegged.

Switching to Emerald stopped the CPU condition and temps have been 
nominal, though I might still call in to get a new fan...
