The MMX chips seem to give a higher bogomips than the PPro ;). Oh
BTW there is a bug if you try and run the SMP kernel on an MMX chip
because its stepping B of a pentium and the kernel blindly assumes
B stepping + SMP + pentium = bug. I've added a patch to avoid this. The
MMX's I've seen don't seen to have APIC's however
