Multihead maximising

I need a single window to 'maximise' across four monitors and I'm hoping someone who knows *nix better than a casual linux user like me can help me out.
I know the ability to treat four monitors as a single screen has been killed by pretty much every graphics manufacturer, since generally it's very irritating. Unfortunately I have a specific instance where I need a program to run this way.

I'm running ubuntu 9.10 with an nvs 450 quattro card. Default nvidia drivers that came with the card, I think they're 190? Compiz is enabled because I need it to remove the titlebar once the app is across all four screens. I've disabled all the compiz feature that I can though.

The closest I've gotten to a workaround was to manually set the size of the window to 5096x768 when the app is called (it has command-line parameters to do so). This worked using a really old Matrox card that was lying around, but this was in ubuntu 6.10 which was the newest distro that supported the card. Anyway, that card isn't an option because it has zero memory and compiz wasn't around in 6.10.

When I manually set the size of the window now though, it only makes it the size of a single screen., no matter what size I choose. Any thoughts on how to get around this? Is it more likely to be something to do with the nvidia drivers, with compiz or with the distro itself, since those are the three things that have changed between the semi-working solution and now.

Thanks, I've already spent tons of time in that thread and its linked howtos. I had to type up the xorg.conf file for the matrox card by hand in vim before I could even see X :p

My problem isn't getting the screens to appear, it's getting the program to automatically start up across all four. Using Xinerama instead of Twinview seems to be helping a little, but I'm still not 100% there.
