Yeah, this was what I was proposing, basically. The only question here is, would anyone want to disable freq decisions on systems with hw feedback? If yes, then you'd need to be able to disable the feedback thing, maybe have a magic value for powersave_bias... Thanks. -- Regards/Gruss, Boris. Sent from a fat crate under my desk.
