(8.04) Two different video cards, 2 X Servers, Maximize spanning 2/3 Monitors

[cmsimike]

Hello all,
I have two Nvidia cards in my box right now, an FX 5500 and a 7950 GT. I've set up each card to have it's own X server (only way I can actually get 2D/3D acceleration to work). I have 1 monitor on my 5500 and 2 on my 7950. I don't mind this setup too much since I will be using my monitor on the 5500 only for communication (email/chat) and using the two main monitors for everything else. My problem is that on the 7950 with two monitors, when maximizing anything, it spans both monitors. How can I limit it to just one monitor?
The two monitors are using TwinView which I think is the problem. When enabling Xinerama, I can use all 3 monitors no problem but then the 2d performance of applications suffers terribly. In case it is of any assistance here is my xorg.conf:

I hope this is enough information and thanks in advance for any help.

I have same setup (Two Nvidia cards on 9.10 - 64 bit). I would like to know how to limit any window to just maximize to one monitor. I remember that use to work under 8.10

Here's one solution:

But it doesn't solve everything (see my later posts in that thread). I'm still searching for a solution for those problems (I'm about to create a new thread about it).
