Bug Description
This happens with the via driver:
bluefox@icebox:~$ glxgears
__driCreateNewS

Error: couldn't get an RGB, Double-buffered visual
The vesa driver reports other libGL warnings I believe, but the same error occurs.
Here is a clip of Xorg.0.log showing DRI is enabled:

----END Xorg.0.log----
This bug is related to (and possibly a duplicate of):
#29493
This bug produces symptoms similar to similar but is fundamentally different from:
#36314 (DRI is disabled in Xorg.0.log)
This bug may affect other open source and binary Xorg drivers.
This Xorg.conf is fresh, but the bug still happens. I'm attaching it and its matching Xorg.0.log.
