Can you show /proc/cpuinfo for the affected system ?
If it's 15/3/4 or 15/4/1, that would explain why this kernel,
as this was when support for those models got introduced to
speedstep-centrino.
If it's not that, there is a pretty large delta in the ondemand
governor in this update, but I don't see anything blindlingly
obvious from looking over it.
