Very interesting. My second display never showed other than solid
black under X without the Matrox drivers. For future archive searchers, 
the name of the package I downloaded from Matrox is

    mgadrivers-2.0.tgz

Which installed the files

   	/usr/X11R6/lib/modules/drivers/mga_drv.o
   	/usr/X11R6/lib/modules/drivers/mga_hal_drv.o

I also checked out Matrox's Linux version of MGA Power Desk 1.0 b8,
which is a gui tool for setting up your displays. It defaults to
enabling Xinerama and had some bugs (swapped my displays left-to-right)
and limitations (sets both displays to same resolution). But for beta
software it wasn't bad, and it did create a dual-head XF86Config-4 file 
with examples of useful settings that ran both heads. 

Someone starting with this tool could probably get things working to
their satifsaction with a modest amount of editing. Very nice to see
Matrox working on this.
