I managed to start X with DRI by changing the radeon driver's BusType
to PCI, and glxinfo now reports

OpenGL vendor string: Tungsten Graphics, Inc.
OpenGL renderer string: Mesa DRI R300 20060815 TCL
OpenGL version string: 1.3 Mesa 6.5.2
OpenGL extensions:

However, glxgears will not run. It just exits with the error

drmRadeonCmdBuffer: -22 (exiting)

DRM_DEBUG output, however, does not contain any error messages.
Am I mistaken that when I run glxgears, it will try to communicate
with the DRM driver directly, and not through the X server?
I'm asking because I only see X server's pid in DRM_DEBUG output.
