I have used one matrox G550 dualhead card, it worked.
I have the impression that the older G400 cards works
better, mostly because they are better documented.

Do you want to run xinerama over several displays, or do you
want to have one independent user per display?  The latter
is a bit trickier, particularly if you want to use
accelerated X (which one usually wants). The problem is that
an xserver tends to grab an entire card.
I believe matrox have some dualhead cards (and four-way cards too)
that solve this because they look like 2 or 4 cards to the software.
They are very expensive though.
