The last time I saw that error was on a -CURRENT test system several 
months ago.  That system is updating now to the latest -CURRENT.  Time 
will not be available for at least the next few days to try 7.1, but 
I'll see what I can do.

The 1.4.9 version of mga may work.  I'd give portdowngrade instructions 
for it, but the anoncvs server isn't answering.

If you have the option of replacing the Matrox card, better-supported 
Radeons are available in AGP, PCI, and PCIE versions.
