Hi,
with tp-control (daemon) script the fan stops also. Or do you not want
to use this script?
Do i have the chance to get the powerstate driver with radeon, to slow
down the GPU? With the fglrx driver it works, but as you know, the
ati driver is broken under Fedora 7.

Also the linux-phc patch is a good thing for T43, i can run the T43
with 30% less voltage in all steps.

CU,
 Joern Rink
