What is wrong with the "abstraction" of having a number of ordered
performance states? Hiding the states behind something pretending to
be a continuum (wether this is a MHz value or a percentage doesn't matter)
causes confusion. You never know what performance state you selected
and you start to assume that 100% is twice as fast as 50% even when
there is no correlation.
