My ibook G4 boots at low speed. /proc/cpuinfo shows 666MHz and a smiliar bogomips value. Nevertheless, the cpu frequency scaler works, i.e. set it to performance to be at high speed after boot up, or, as I currently do, use the userspace governor and powernowd. All this is without your patch (Did not try it yet, my ibook lacks internet) on linus' 2.6.11.
