Well.......... i got a turion on my laptop myself, and the powermanagement does
not work. The fan sounds like a jet engine, and it does not go down. The CPU is
unable to go idle and stuff, which makes it unable to go down in tempratur,
from when the PC is booted it will continue to slowly increase its tempratur.
Running Ubuntu 9.04 with standard generic Ubuntu kernel. cpufreq as deamon to
regulare, with the autoload from cpufrqutils which should have made it work.
