I checked in there, and the only reference at all was in firstboot,
which checks for the existence of xorg.conf and launches the
configuration script if it isn't there.

I'll check this next time as well if I can remember.  I also took
Christoph's suggestion and turned off Kudzu.  Most of the time my
hardware configuration is fixed, so there's no need to run it on each
boot.  This should speed up the boot process by a bit too.
