I removed snd-powermac from /etc/modules and removed the blacklisted snd-aoa* modules and rebooted. It loaded the snd-aoa modules and it's working. Should I file a bug or add this information to bug #650588? How can I find the exact version of my iBook G4? All I know is it's one of the latest ones.
