hi,
i've got an ibook 2.2 with PowerMac Snapper (Dev 24) and i'm getting nearly
the same problem. I'm going to try your patch, however i'd like to know if
anyone has encountered this kernel oops:

I see this oops when gtkpbbuttons tries to "beep" (e.g. low battery alarm);
of course after this everything alsa/audio-related doesn't work.
TIA
