I seem to recall hearing that you could throttle back the cpu on a powerbook to help conserve battery life. I tried a few searches but came up with nothing.
I have a 1 ghz Tibook, if you needed to know.

yes you can. It's an option in the Energy Saver control panel of System Preferences.

Does anyone know exactly how much power this saves? Isn't CPU a relatively low power draw compared to optical drives, hard drives and screens? can you increase battery life by, say, more than 10% by reducing the processor speed?

Short answer is "yes"...chip frequency is one of the big energy drains. The backlight is also a big one.
