With sysctl hw.cpufrequency you'll always get the maximum or the reduced processor speed regardless of the settings in the "Energy Saver" panel.
At the moment the only tool which reports the actual cpu speed correctly is Apple's Skidmarks GT (included in the CHUD Tools).

sysctl hw.cpufrequency does not work properly - cksample3
I'm not really sure if the poster of this comment understands that I'm only trying to get the maximum processor speed (b/c if it is lower than it should be it is a problem). It is supposed to be diagnostic for the singular problem of a PMU that needs resetting, not as a processor usage monitor. I made the script based on information that I found on the 12-inch Powerbook Yahoo Group (as I stated here). As I understand it, it is working properly for what it is intended to do. Can anyone provide more info on sysctl hw.cpufrequency? --C.K.Tuesday, November 18 2003 @ 05:02 PM PST

I realized that my description of the scripts was too vague. I've revised...Tuesday, November 18 2003 @ 05:14 PM PST
sysctl hw.cpufrequency does work for this script... - cksample3
So, the CPUfrequency scripts work fine for what they are meant to do, which is simply to report the maximum possible number (speed in hertz) your computer currently thinks the processor is capable of achieving. If it reports back 5333333334 and you have an 867mhz chip, as happened with me earlier this week, then your PMU needs to be reset, so that the computer will realize that there is more processing power available there, should it be needed...--C.K.
