  Oh, I meant to mention something else.  You can force a clock source
change by writing to current_clocksource with:

echo tsc > current_clocksource
echo hpet > current_clocksource

  I did just do a quick lookaround at the CLOCKSOURCE_WATCHDOG option,
and there seems to be an awefull lot of reports of issues with pretty
much every type of clock source out there between 2.6.16-2.6.25.

  Seems like searching google, I can find bugs of each and every
clocksource.  LOL.

  I say, it's time to go to clockless processors!  :-D
