Boy, I wish I could laugh at this... :( Just kidding...
Ok, here's my situation (R50): So far the only solution to stop the fan from 
running ALL the time with Linux is compiling the latest ATI Driver (which is 
not open and therefore not everybody's first choice) which has the energy 
saving features. It works better than the original XFree Driver.  I am also 
using speedstep with a 2.6.7 kernel. That way the fan pretty much behaves 
like under Window*, which is far from being what you expect from a machine 
that expensive. Oh - the latest Bios-Update (don't quite remember now which 
version) solved the problem with the fan running a little faster every 4-5 
seconds...
