On my laptop:
% sysctl -a | grep freq
machdep.est.frequency.target = 1000
machdep.est.frequency.current = 1667
machdep.est.frequency.available = 1667 1000
% sysctl -w machdep.est.frequency.target=1000
machdep.est.frequency.target: 1667 -> 1000
% sysctl -a | grep freq
machdep.est.frequency.target = 1000
machdep.est.frequency.current = 1000
machdep.est.frequency.available = 1667 1000

also:

I guess my dmesg also may be of interest, so it is attached.
