Eero, I see in Profile_CpuUpdate that we have :

       cycles = CyclesGlobalClockCounter - cpu_profile.prev_cycles;
       cpu_profile.prev_cycles = CyclesGlobalClockCounter;
       cycles <<= nCpuFreqShift;

IIRC, that's some code I sent you, but i it could be wrong, I don't 
think the << is needed, else we don't keep consistancy with the traces 
from disasm.

I will have a look at this and let you know.
