We believe you :) After much pulling teeth in -stable, Warner Losh had
already hit the bullseye regarding Martin's other problem (clock losing
time beyond ntpd's ability to cope when running powerd) in this post:
http://lists.freebsd.org/pipermail/freebsd-stable/2007-May/035068.html
where he suggested bumping debug.cpufreq.lowest up past 300MHz or so,
where Martin's t42p was shifting down to 75MHz at idle (with HZ=1000)
Glad that's sorted ..
Cheers, Ian
