Hi, i got this week my new ibook. i know, there is a kernel freeze, but nonetheless i will report a patch i found on the debian-powerpc mailinglist.
the psnd_powermac module detect the wrong soundcard. the new ibooks have a snapper. the solution seems to be, to add additional "case 0x50" (patch from Sven) or/and "case 0x5c" (patch from the link), to detect snapper correctly. I just want report this. So unfortunally Breezy wont support sound over speaker on newer ibooks. i had report it before the freeze, but apple was so slow with delivering my order ;-) I paste the mail from debian-powerpc..
