Synopsis: add Matrox MGA Driver to xorg-server

State-Changed-When: Thu Jan 13 20:52:48 GMT 2005
State-Changed-Why: 
I've committed an mga_hal port in x11-servers which I believe does all that's
necessary for MGA HAL support, without cluttering up xorg-server.  (I read the
diffs and didn't see things that seemed too major, but please tell me if there
are pieces of Matrox's code that are necessary).
