It's equally meaningless (in fact, less meaningful). - By your definition my 900MHz VIA C3 is faster than my 800MHz Athlon. (Clue: It isn't). - With trickery like AMD's quantispeed ratings, MHz really is a totally meaningless number when relating to performance of a CPU. - A MHz rating is only meaningful across the same vendor/family of CPUs.
Getting cpufreq's policy interface into something CPU agnostic therefore precludes MHz ratings AFAICS.
