# echo "modprobe snd_powermac" >> /etc/rc.local
reboot, check the settings and all is ok

On my Powerbook G4 Ti 867MHz, sound worked after I added the following 
to /etc/modprobe.conf:

alias snd-card-0 dmasound_pmac
install dmasound_pmac /sbin/modprobe --ignore-install dmasound_pmac && 
/usr/sbin/alsactl restore >/dev/null 2>&1 || :
remove dmasound_pmac { /usr/sbin/alsactl store >/dev/null 2>&1 || : ; 
}; /sbin/modprobe -r --ignore-remove dmasound_pmac

I've no idea what's the difference between dmasound_pmac and 
snd_powermac (but I'm sure I'll have after some googling) and I didn't 
try the other. /etc/sysconfig/hwconf says snd_powermac for me too (but 
I didn't know about that file before you mentioned it).

dmasound_pmac is the OSS version, snd_powermac the ALSA version.

Right, I figured that out. And I also figured out that OSS seems to be 
old and ALSA a new-and-improved replacement for it, so I tried 
replacing dmasound_pmac with snd_powermac in modprobe.conf, and that 
worked too.

It only works halfways though, at the moment - I've discovered that 
XMMS and Mikmod can't produce sound at the same time (didn't try any 
other apps). But I'll have to read more about how sound works on Linux 
to try to fix that.
