Cannot directly answer, but I can give you some possibly-helpful info.

Matrox cards are the best for doing dual-head on all-PCI machines. It
was a design feature of them from 10yr ago or more. I have run
dual-head Matrox PCI machines with WinNT, Win98 and Linux - and it
even worked in OS/2 in theory. (Of course, in W2K/XP it's very easy
and these OSs can do it with virtually any combination of cards.)

However, if Matrox did offer dual-head single cards, I don't know of
them and they were expensive.

Two Matrox cards of the same family should work a treat, will be
inexpensive and offer good performance. I'd even send you a matched
pair of cards - I have half a dozen or more now - but I'm in the UK
and it would probably prove unreasonably expensive!

SuSE made setup very easy. Xandros is also very good at configuring this.

I used to run a dualhead Matrox G550 AGP under Ubuntu 4.10 but I got
it working by copying a working xfree86.conf file from my SuSE 9.2

I found it quicker to install one of them, set it up to suit, and then
steal its config file for Ubuntu or Red Hat or some other distro that
didn't understand dual-head itself than to try to hack the config file
appropriately by hand.
