This is most probably unrelated to CPU freq and powernow-k8 driver.
I expect the backtrace does not always point to powernow-k8 driver?

I saw something similar, also related to the X driver.
It was very hard to reproduce (run two different 3D X applications in parallel,
then it would throw such an MCE after 2-30 minutes...) and hang up.
The fix was about missing TLB flushes related to ioremap.
