I can vouch that it would be worth it; I just commented out the test
for multiple lo table entries and the modules loaded fine:

powernow-k8: Found 1 AMD Athlon 64 / Opteron processors (version 1.00.08b)
powernow-k8: Too many lo freq table entries
powernow-k8:    0 : fid 0x8 (1600 MHz), vid 0x6 (1400 mV)
powernow-k8:    1 : fid 0x0 (800 MHz), vid 0x18 (950 mV)
powernow-k8:    2 : fid 0x0 (800 MHz), vid 0x18 (950 mV)
powernow-k8: cpu_init done, current fid 0x8, vid 0x6

I then can do this:

I didn't even realize I'd been stuck in "low gear" this whole time.
