Of course ;) The problem here is about that specific machine model
for which I'm not sure what frequency I will get after asking a
speed change to the Power Management Unit
(it seem it will be 300Mhz, but I want him to try the debug stuff I
added that will redo the bogomips measurement so I can verify it's
actually 300Mhz).
