Debian maintainers activated the gallium one in the meantime: martin@shambhala:~> glxinfo | grep OpenGL OpenGL vendor string: X.Org R300 Project OpenGL renderer string: Gallium 0.4 on ATI RV350 OpenGL version string: 2.1 Mesa 7.10 OpenGL shading language version string: 1.20 OpenGL extensions: I think I tried the desktop cube with the gallium one already, but I am not absolutely sure. I have a 2.6.37 kernel still at hand and will test with just changing the kernel.
