I would say comment out drm. Of coarse with the minimal file, how would 
you do that. You might try to drop to runlevel 3 and try your luck with 
"X -configure' to see if it generates a working X file that is 
substantial enough to prevent the guessing game. The file is generated 
in /root/ directory with what command to use to try out the 
configuration file. You then can copy the file to /etc/X11/xorg.conf if 
it works for you. If it does, there should be a modules section.

There was this excerpt from your log on the one bug report. Also I 
recall some information about a specific entry in some out of the 
ordinary file from Adam I believe referring to a new file which might 
need configuration. I could not find it due to site maintenance.
  There is an
/usr/lib/dri/r300_dri.so module. I believe you specify this driver in 
the file with reference somewhere in the archive.

I hope this response at least gives you some ideas to try.
