Does anyone know if the current IBM 970 chips in dual G5 Powermacs and 
Xserves is under any clock frequency
scaling control? In other words, is the clock freuquency always 
guardanteed to be the nominal, or it may change
based on temperature? If this is the case, does the linux kernel have 
any control on it?
