I use a Matrox G400 AGP, works great with the blackbox window manager 
which I have to plug with Sean on the thread. I run the CVS build of 
blackbox, running a seperate server on each display which I like better 
than xinerama since my displays aren't a matched set.

Only downside is video RAM: I have the 16 MB card, can run my 17" 
display at 1152x864 and the 15" display at 1024x768 both in 16-bit
color, not enough RAM for 24-bit.  Since I have some extra 8 MB cards 
lying around I'm considering popping one in to run the 15" display and
have 24-bit color on both.

I've also installed the Matrox framebuffer stuff which I _don't_ use for
X, but when not running X I have some very nice looking fonts and 132
char lines. And the penguin, of course. I only get a term window on my
primary display, the other shows abstract art until I start X. YMMV.

Gotchas:
- Took me a long time to get it running, solution was to download and
	install the drivers from the Matrox website. There are very good
	dual-head XF86Config-4 examples out there.

- Every so often an apt-get update will fry the drivers and X quits
	starting. The solution is to reinstall the Matrox drivers, but the 
	the installation script will only run from an xterm (WHY!?).
	
	Solution is to run xf86cfg, and play with it until I get into twm and 
	can open rxvt, then I can run the Matrox install script and all is well 
	again. Suggestions for how to avoid this entirely are very welcome.
