The various combinations are quite numerous. It all comes down
to pixel depth.

Onyx IR gfx, One RM, 1600x1200_60 == small pixels
Onyx IR gfx, Two RMs, 1600x1200_60 == medium pixels

With small pixels, one of the available formats is 4-sample ms,
15-bit Z, 1 bit stencil, 10 bits/component RGB, double buffered.

With medium pixels, one of the avialable formats is 8-sample ms,
23-bit Z, 1 bit stencil, 10 bits/component RGB, double buffered.

I'll append a more complete list below. I believe this might be
slightly out of date, but it is correct enough to use as a rough
guide. Also note that it was originally created for Onyx IR, not
Onyx2; and also might be slightly changed in the current patch sets.
