If none is present, a default one will be created. This will be attached
to either the first device section in the xorg.conf (allowing you to
specify something like using EXA without having a screen section) or a

This is what we're currently shipping in Debian. Enables the ability for
drivers to ship a text file listing PCI ID's they support, and have the
server read them on startup when no driver is specified. This works, but

Add XSERV_t, TRANS_SERVER, TRANS_REOPEN to quash warnings.
Add #include <dix-config.h> or <xorg-config.h>, as appropriate, to all
source files in the xserver/xorg tree, predicated on defines of
HAVE_{DIX,XORG}_CONFIG_H. Change all Xfont includes to
<X11/fonts/foo.h>.
