Maybe. This power saving mode didn't help /that/ much for me.
I started writing a driver for the thermal monitor / fan control chip in my iBook G4, so far it can only read various sensors but I plan to add something to change the fan controller's settings ( so you could have the fan spin up at lower temperatures - provided your PowerBook uses the same chip, an Analog Devices ADT7467 )

have fun
