Try installing powernowd for cpu frequency scaling. It runs great on my 
T42p with the following options: -q -m 0 -l 50 -p 500 -s 200000

In addition, get the Dynamic-Clocks Patch for your X server, so the radeon 
chip does not run full speed all the time (the fan is cooling both CPU and 
GPU)

With both installed and the notebook (almost) idle, I get extended periods 
of total fan silence.
