I don't think Ani is on this list, but it doesn't really matter as I know
what's going on :)
aty128fb is broken. Even when it's told to use depth 16, it uses 15 in fact.
D'oh.
I've tried fixing it, but failed in my first attempt. Brad Douglas, the
current aty128fb maintainer, said it should be easy to fix and that he would
contact me on the fix. Hasn't happened yet...

So atyfb is probably broken as well.
Depth 16 does work in the DRI ppc-1-0-0 branch without Option "UseFBDev". It's
also got options to override panel dimensions to enable Pismo users to use
several resolutions.

Peter, have you verified that matroxfb works as fb0?
