I have also seen this behaviour on our mailserver running Ubuntu 7.04 Server. I just commented out the following part of /etc/init.d/powernowd (lines 108-112):
if use_ondemand
then
log_end_msg 0
return 0
fi
Seems to work for me, powernowd is running according to ps and frequency scaling behaves as i wish.
