I'd like to test this out with nouveau as well... do I understand
correctly that I shouldn't need anything special to check if it
basically works? i.e. I apply the patches, start Xorg in bpp=30 mode,
and then if glxgears works then I'm done? Is there a good way that I'm
really in 30bpp mode as far as all the software is concerned? (I don't
have a colorimeter or whatever fancy hw to *really* tell the
difference, although I do have a "deep color" TV.) If used with a
24bpp display, is the hw supposed to dither somehow?
