There is a bug in Red Hat's bugzilla and I talked with various xdevs about
this, but it is not trivial to fix for them, or so I've been told.

Also we don't need to fix all games, most use a handful if libs, for
Fedora those 3 patches are all that is needed.

Also note that xf86vidmode is considered sort of deprecated by upstream xorg,
so the chances of getting this fixed there are not too good.
