That's not true.
cpupm mode can be changed by pmconfig on the fly.

Should've been more specific in my reply, so:

% vi /etc/power.conf  # Change to poll-mode
% pfexec pmconfig

% pfexec powertop # shows proc. always at max speed % pfexec reboot # After the reboot, powertop shows proc. at lower freq.

It is either a bug or your system isn't idle enough for poll-mode to lower the freq. either. I have successfully switched event-mode and poll-mode many times without a reboot.
