I did some investigating this morning and found that there is a version
mismatch between the breezy xorg server and the binary MGA driver from the
Matrox site.  Some googling turned up this page:

The post from _cato on 10-31-2005 explains how to solve the problem: fetch
and unpack the xserver-xorg-driver-mga package, copy the included mga_drv.o
into your active system, and restart X.

This seems to work for both 16-bit and 24-bit depths.

Also note that I have VGA outputs, I don't use DVI.
