Status of snd-powermac?

[Anders Gudmundsson]

I hope this is the right forum for this question...
A number of TiBook/iBook users running post 2.6.20 kernels has been
affected by a bug related to the snd-powermac driver for Pmac Snapper
cards:

Short summary:
snd-powermac loads (specified in /etc/modules)
Sound is produced for a randomly short period never exceeding 5 seconds,
then stops. No errors are given (even if the drivers are configured with
debug), the application hangs and blocks the sound device.
No matter what versions of alsa-libs or alsa-drivers used, the bug
persists. (Only booting a pre 2.6.20 kernel helps - or using the old oss
dmasound_pmac driver) 

My question:
Is the snd-powermac driver to be phased out for the snd-aoa, and is
support planned for older cards (PB IV, G3 iBooks etc.) in snd-aoa?

Regards!
