[Xorg] getconfig.pl

[Erik Harrison]

I was frustrated the other day by my seeming inability to learn C. As
I actually speak Perl and was hoping for some distraction, is started
to poke around in getconfig.pl.

getconfig has a small list of PCI ID to driver mappings inside the
program itself. Considering that we install a default xorg.cfg file,
is it really sane to keep this information in getconfig? I could move
it out into xorg.cfg if it's the Right Thing.
