Hi,
I've just tried out the r300 driver - works remarkably well for
"untested and
broken" code.

I've run into 2 bugs though:
It doesn't work well if the display uses 16 bpp (24 bpp works
perfectly) -- 3D
in 16 bpp is pretty badly misrendered (sample attached; 2D works well
w/ r300
DRI even at 16 bpp) -- mixed with a random section of the rest of the
screen,
wrong colors, and drawn way too large (but close enough to the expected
output to recognize it).
I don't think we ever focused on getting 16bpp right - having 32bpp
working is fun enough :) Also, all of r300 and later cards have more
than enough RAM for 32bpp modes.
That said, it is probably just a matter of making sure some constants
are set properly (like colorbuffer parameters), I don't think anything
else in the driver is tied to that.
If 16bpp isn't supported, the DDX and/or r300 client driver should be
modified not to try, and just fall back to indirect rendering.
