Setting up one independent monitor and one clone pair?

Fedora RedHat Enterprise 5
X version 7.1.1

I've been digging around for a while to try and come up with some solutions, and I'm finally caving and asking for help.

I have two PCIe nvidia cards, each with one DVI and two displayport outputs. I'm trying to set my displays up such that:

GPU-0: DVI: Primary screen, DisplayPort-0: Nothing, DisplayPort-1: Nothing
GPU-1: DVI: Seperate X-Screen, DisplayPort-1: Clone of Seperate X-Screen at higher refresh, DisplayPort-2: Nothing

Thus far I'm having a LOT of trouble even getting anything to appear on the displayports on GPU-1 at all, much less a cloned image. Here's the general idea of what I've been trying:

Set up a section "monitor" for each of the screens we want. Set a Modeline customized with the resolution / framerate we want for each.

Set up three section "device"s, each tied to a BusID; one is tied to BusID 6:0:0, two are tied to BusID 4:0:0.

Set up three section "screen"s each tied to a monitor/device combination above.

Here's what the xorg.conf currently looks like (some parts intentionally blanked out because of proprietary issues)...

Code:

I know it's a gigantic mess right now as I've been experimenting a lot. If someone can suggest a basic skeleton xorg.conf for one x-screen on GPU-0, one display on GPU-1 cloned onto ANOTHER display on GPU-1 (preferably with a different frequency), it would be much appreciated.

I use Ubuntu and allow it to automatically configure the display screens (on a laptop.) The only thing that doesn't look right to me is the identifier "Single Head Configuration" since it seems that you actually have a dual head (2 display cards) system. You may want to see if you can get your OS to automatically configure the displays and then look at the configuration files to see what settings it has and adjust those settings to get what you want to see on the screens.
