I don't know if this will help in your case, but this method worked my iBook G4 with a failed logic board.  Try alt-booting until you see a blue screen with an arrow on the right, and a sort of bent arrow on the left.  Once the cursor turns from a watch to a regular pointer, press and hold the "eject" key.
