Replying to my own post, it appears that the documentation needed would be:
...and the original OSS code:
Headers in that OSS source suggest that the existing snd-cs5535audio
from the vanilla 2.6 kernel could be extended to support the whole
Geode line's audio.
If that's the case, the port could easily be skipped and instead
adding addtional ifdefs and device IDs to the snd-cs5535audio driver
might be all that's needed.
Anyhow, Geode use standard AC97 codecs, so that should be fairly
straightforward to anyone familiar with AC97 coding on ALSA.
