Try resetting the PRAM through Open Firmware:

Boot Mac while simultaneously holding CommandOption+OF

When at the command prompt type the following:

reset-nvram <Enter>

reset-all <Enter>

The Mac should now reboot into OSX with a reset PRAM.

I know I can do that but I want to know if the Command+Option+P+R actually does work thanks D

I just tried it on a 12" G4 1.33 and I could zap the PRAM with keyboard commands. Also tried it on a 12" iBook 700 MHz and it works.
