i belive with propper cpu freq scaling that the bogo mips gets recalculated, ascacko just changes a few registers and dosent tell the kernel the kernel reports the worng thing
one other thing that may be of intrest, i have heard that the c3000 range over clock better than the newer models, i know i gan get up to about 690Mhz on mine (by fiddling with the freq registers by hand) but i get about 2 hours of battery life
