I was going to take a look, but apparently we don't have the cube_map
extensions hooked up, and I'm not sure how to do that with Mesa and
Gallium, and also there are no cube map tests in progs. Do you have a
patch and some test code? I don't know why it wouldn't work, cube maps
should work with the auto mipmap generation method they're using in
Mesa currently.
