OK, I just installed Linux on the machine and patched 2.6.8 successfully, but I'm getting a a "No such device" because the powernow_decode_bios routine never finds the "PSB Header". I have no idea what a PSB header even is. Do I need to fake the PSB header information as well? Or is there a simpler way around this? I also attached the dump of x86info. I'm not sure why it's telling me FID changes won't work; it's looking at some FIDC bit in an MSR... This wouldn't affect cpufreq would it?
