Are you sure?  Decoding the msr value above, your frequency/voltage
range is (800MHz, 988mV) - (2000MHz, 1308mV), so I guess multiple
entries(600MHz and 800MHz, for example) end up in the same CPU
performance.  NetBSD people seem to be using `openssl speed' to
measure the performance for each setting.

Cheers.
