I thought that even DRI shipped with XFree86 4.3.0 needs at least
a 1.3 radeon.o DRM kernelmodule. (someone should verify)
Just export RADEON_COMPAT=1 and try glxgears. -> assert

shouldnt agp-texturing just get disabled when an older kernelmodule is detected
that doesnt support that necessary call ?
