I have been using three monitors connected to two graphics cards (and a
projector, so make this four monitors) as a single X screen.
All it took were two NVIDIA GT8600 and Xinerama.

The reason I'm not running this setup anymore has nothing to do with the
setup itself rather than my preferences.

There is also a "Mosaic" mode which is supported by even the cheapest
Quadro cards (around 100Euros each). You could take a look at the NVIDIA
driver documentation to see if it fits your needs.

When I last tried Xdmx it worked quite well like advised in the manpage.
It didn't support rotated monitors, though.

The reason that Xdmx lacks a mailing list is that Xdmx went into
Xserver. So you might want to ask your questions on the Xserver ml.
However, from what I saw, there is not much active development around
