This subject seems bare to say the least. I have only read 1 or 2 comments in regards to people saying they can no longer adjust the processor performance in the Energy Saver settings under system preferences.
someone else posted a link to the developer notes for the new pb's. it basically states this:
it almost sounds like apple has taken away the ability to set the processor performance and they are doing it for us. i am not sure if i like this.......
anyone else have anything to chime in?
thanks

Processor Power Management
To lower power consumption and heat generation, the 17-inch PowerBook G4 incorporates an automatic power management stepping technique. Stepping is designed to run at full, half, or quarter processor speed and voltage to meet the demands on the processor. The processor speed will switch between 1670 MHz and 833 MHz at 1.30 V for divide by 2 and between 1670 MHz and 417 MHz at .93 V for divide by 4. The memory bus speed is not shifted.
If the 17-inch PowerBook G4 detects a system temperature that is high, due to high ambient temperatures or other factors, it will immediately force the system to quarter speed mode.
The 17-inch PowerBook G4 meets all applicable safety standards, including UL 60950 and IEC 60950.
Graphics Power Management
For additional power savings and reduced heat generation, the 17-inch PowerBook G4 incorporates a dynamic graphics power management technique. When required, the graphics processor runs at a reduced voltage and slower clock rate, similar to stepping on the central processor.
