Please post the output of "glxinfo | grep radeon_get" with this mesa patch.

Only this line is printed: radeon_get_num_backends: 0 2

I *think* the problem is that linux 3.0 only uses version 2.10 of the kms wrapper, where as the call to radeon_get_backend_map(radeon) in r600_drm.c only happens when the minor version is >= 11.

Just changing this value to 10 both makes the second line appear (radeon_get_num_tile_pipes: 0 4) and gets working 3D again, but I guess I really need a later kernel :)
