When you apply this patch to the kernel source and recompile 
the powernow-k8 module it will likely work. But it's still unclear why 
your CPU has such a weird signature, different from other CPUs. I am 
still suspecting some BIOS issue, because part of the CPUID information 
is supplied by the BIOS. Trying it with a different mainboard may
be a good idea.

You didn't send me the output of the test program I sent you yesterday
btw.
