I'm running Debian squeeze on a 12" PowerBook G4 and these are some of my notes about the configuration. This is may not work for your hardware so take with a grain of salt.

Sound
For some reason or another after installation the snd-aoa driver is the standard driver on the machine. But there is not a single sound escaping the speakers with that driver. As written on the page of the snd-aoa driver the machine in quesiton PowerMac6,4 is not on the list of the supported Macs anyways.
I had to do a bit of fiddling by blacklisting the snd-aoa drivers and manually loading the snd-powermac one.
Firstly we add the snd-powermac to /etc/modules. Each module defined in the /etc/module file will be loaded at boot time.
echo snd-powermac >> /etc/modules
And confirming
grep snd-powermac /etc/modules
snd-powermac
Next is to blacklist the snd-aoa modules in /etc/modprobe.d/alsa-base-blacklist.conf
grep --color snd-aoa /etc/modprobe.d/alsa-base-blacklist.conf blacklist snd-aoa-i2sbus blacklist snd-aoa-soundbus blacklist snd-aoa-codec-toonie blacklist snd-aoa-codec-tas blacklist snd-aoa-codec-onyx blacklist snd-aoa-fabric-layout blacklist snd-aoa
After the next reboot sound should work fully.
