Crap,

I assumed it'd work as it works on my machine. Maybe your BIOS' behaves differently from mine or Phenom II CPUs are differently initialized (P1 seems to be disabled in the registers). I'll add a check for this in the next version (but I'm going to bed right now, gotta wait). I'm afraid you're most likely unable to activate higher P-states manually. Do the few hundred MHz on the NB rationally justify wasting lots of energy (I assume your CPU idles as much as mine)?

As I think about it: there'd still be a way for manual switching. This involves applying temporary settings (like AMD OverDrive), but I've got to perform some tests on my machine first. Stay tuned.
