That would be the PowerBook 5,9 (confirmed working, that's what I have).

When writing documentation, you might want to add that the ALSA-plugin
in XMMS & Audacious requires a period time of 100ms instead of the
default of 50ms, as otherwise the sou*click*nd is n*click*ot ver*click*y
good.
(A look at the current code of that plugin, to see how the volume
control code can be fixed would be highly appreciated)

Much appreciated, thank you :)
