The issue is that Maya is requesting at least 23-bits of Z-buffer. In
16-bit mode, we only have 16-bits of Z-buffer, so it can't find a visual.
On the Radeon, is depth bpp == color bpp a hardware limitation or just the
way the drivers were done?
In other news, I tried (using CVS as of the morning of 4/9) running in
1152x864 and "maximizing" the Maya (so that it would fit) and running in
Maya's expected 1280x1024. In both cases, I hit the following assertion:
radeon_vtxfmt.c863: radeonFlushVertices: Assertion `vb.installed' failed.

I can try to provide any other info that might be helpful. Just let me know
what is needed.
