The only place that '/dev/mem' is referenced to in the source of the
program is an open() call, to see if the device exists. XF86DGAGetVideo is
called just after. 'strings libXxf86dga.a | less' shows '/dev/mem', but no
'/dev/xf86'. Sounds like XF86DGAGetVideo doesn't have a choice; does this
mean our X server is broken?
