Xorg.log without configuration file

Without xorg.conf or with a pixel depth of 24 bits, any application linked to libGL will fails to load the "r300" driver and after it the "swarst" driver with the following message:

  libGL error: failed to load driver: r300
  libGL error: Try again with LIBGL_DEBUG=verbose for more details.
  libGL error: failed to load driver: swrast
  libGL error: Try again with LIBGL_DEBUG=verbose for more details.

This problem is present in all the Mesa 9.x release up to 9.2.3. But it is not in the 8 (which segfault at some point), 7.11 was working without config file.

After a bit of investigation, I found that driConvertConfigs() returns NULL in dri2CreateScreen() when trying to find matching visuals (src/glx/dri_glx.c:450). However if I specify a depth of 16 bits in my xorg.conf I cannot reproduce this problem.

This problem is present on OpenBSD -current (future 5.5) which has the drm drivers synced with Ubuntu's linux 3.8 kernel.
