s-c-display led to a blank screen with my MGA G200 card initially. I 
found out that either running with no xorg.conf file or generating an 
xorg.conf file using 'X -configure', testing it as the prompt specified, 
then copying it over if it is successful during the test. This 
configuration is needed to be accomplished at runlevel 3 since X cannot 
be running prior without getting an error.
I had to edit the configuration file and limit the vertical range to 
lower than the 190 maximum that it was specified as.

Attached is my xorg-conf file. It is a bit odd since I am using the 
matrox card as primary. (It does not work very well as the secondary on 
two different computers). You might try this for comparison referencing 
the video parameters and vertical refresh rates.

As you noted, Matrox video cards are out of the ordinary for usage in 
win32 and for Linux. Linux seems better with dealing with the cards than 
early win32 versions were.

Radeon cards and OSS drivers worked better for me with 3D applications. 
I only tried this on a laptop with integrated graphics though.

Attached is my xorg.conf. This should have most of your needed settings 
for video card 1.
