I would like to drop all of this dexconf logic at this point.

Today I have added code to the xserver which should automatically detect
and select the correct driver for qemu and vbox cases.  I've also added a
patch to the cirrus driver which should configure 1024x768 on the kvm

Thus, I believe all cases currently covered by dexconf hacks now should
be automatically handled when no xorg.conf is present.

Next step, I would like it if people could please confirm that kvm
(cirrus), qemu (non-cirrus), and vbox all work equally well with no
xorg.conf as when the dexconf-produced xorg.conf is present.  If this is
the case, then I can proceed with dumping the dexconf hacks.
