OK. i'll look at the bugzilla. But i can't remember any slow-down or 
hicup on my machine with p4-clockmod so far... It just scales perfectly 
when needed.
I didn't measure the power gain thus.

i suppose i don't need to send it anymore, 'cause of desktop PC. but i 
can still if you request :)

say : " Your machine supports frequency scaling, but p4-clockmod is 
disabled on your machine, see 
https://bugzilla.ubuntu.com/show_bug.cgi?id=7259 for more info."

Thanks for your answers !!

best regards,
