[ale] Matrox chipset support for XFree86

[tis3 at cdc.gov (SanMillan, Todd)]

I have an *old* Compaq video card with a Matrox chip on it.  The info on the
chip itself is:

     MATROX
     MGA
     Power Graphics
     IS-Athena-R2
     9522KK003

The docs I have found so far refer to other chipsets for the Matrox server
(e.g.. MGA1064).  Anybody have any idea what this chip is equivalent to or
what servers will support it?  So far it runs under VGA16 fine, but I would
obviously like to move up at least a few steps (like larger than 640x480 and
at least 256 colors)
