You might want to have a look at bug reports https://bugzilla.redhat.com/show_bug.cgi?id=505837 https://bugzilla.redhat.com/show_bug.cgi?id=518377 which dealt with this issue some time ago. Module p4-clockmod does not provide a true frequency scaling as available on systems which support SpeedStep.
