(Get the code!)
I have discovered that the nvidia driver locks the card in the highest performance mode when you have an external monitor enabled (which I usually do), which causes it to run very hot. When I am running just with the built in screen the card correctly declocks itself when doing normal "desktop" 2d work. Due to the fact that the GPU and CPU share a heatsink on this machine (T61p)... higher GPU temp most definitely affects CPU temps as well.
I'm not sure if the external monitor/high performance mode is a bug or a feature... it seems unnecessary to me though.
