Thanks again. Looks like I used the wrong 2d driver patch before
(xorg680.atipatch.r300). Now the glxinfo output looks right:

OpenGL renderer string: Mesa DRI R300 20040924 AGP 4x NO-TCL

However, glxgears only prints out this messages and exits:

disabling 3D acceleration
drmCommandWrite: -22

Hm, this looks funny (from r300_context.c):

       if (1 ||
           driQueryOptionb(&r300->radeon.optionCache, "no_rast")) {
               fprintf(stderr, "disabling 3D acceleration\n");

Is this intended behaviour? I thought the r300 only exists to provide
3D acceleration.

This probably turns on software fallback for most of the calls. Only the few - non-drawing calls are accelerated.


                     best
