PBG4 2.6.9 sound module config

[Pander]

Hi all,

The sound on my PowerBook G4 was working quit oke until I upgraded to 
from 2.6.8.1 to 2.6.9. Think there is something wrong with the loading 
of the modules.

Can anyone with good working sound on a PBG4 2.6.9 GNU/Debian testing 
send me some pointers or files like:
/etc/modutils/*
/etc/modprobe.d
/etc/modules.conf

Mainly stuff on sound and also bluetooth.

Thanks,

Pander
