Based on my experience on RHEL Beta1, "Xorg --configure" will create
xorg.conf which you can then tweak and use. On older Intel graphics chip
I had to use "nomodeset" kernel option to have normal picture.
New Xorg tries to read EDID information from monitor but monitor makers
EDID code is not always compatible with what Xorg expects. That is why
you get only minimal resolution and need xorg.conf file.
