>Description:
Setting CPU frequency to 600 does not seem to be supported, as the current frequency is still reported as 1500

# sysctl -w machdep.cpu.frequency.target=600
machdep.cpu.frequency.target: 1500 -> 600

# sysctl machdep.cpu.frequency
machdep.cpu.frequency.target = 1500
machdep.cpu.frequency.current = 1500
machdep.cpu.frequency.min = 600
machdep.cpu.frequency.max = 1500
machdep.cpu.frequency.available = 600 1500

 With 10.0 RELEASE, it seems to work for me.  Please update, re-check and comment if fixed or still troubled.
