hi, I didnt read this thread from the beginning, and got confused with
so many modules. i have a Turion X2, and -CURRENT on it. If I'd like
to use that powersaving features, and frequency change capabilities (
I had a Pentium M based before and it used to work really fine, 6.1R
in that time) now with this turion, what modules should I load ? it is
possible to know this list, apart from trial and error ?

thanks in advance,


We will call you cygnus,
The God of balance you shall be
