[time-nuts] CPU frequency and NTP crazyness.

the bios lists them as power saving or "green" features.  they will not
reference speed directly.  try disabling anything that remotely implies
power saving.  The best solution I know of though is to use linux as an ntp
server and set a fixed processor speed directly.
