Xorg.0.log (startx without xorg.conf)

Description of problem:
Fatal server error if runlevel 3 startx without xorg.conf. Gfxcard is Matrox G400 (rev 04). CRT display has dysfunctional DDC.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.ensure /etc/X11/xorg.conf does not exist
2.runlevel 3
Actual results:
Signal 11 server abort

Expected results:
X just works

Additional info:
I don't use Fedora much since bug 430836, but I tried to follow up to bug 448945 on another machine and found this. With the xorg.conf file I created by editing the result of system-config-display last October, X always runs without a startup crash. If I try to create a new xorg.conf with system-config-display, I get a crash similar to that starting with no xorg.conf.
