XGL is the only thing I am aware of that will allow you to do 3d type stuff over multiple video cards.

I am not sure how helpfull it will be to you but you can look at my Xorg.conf as an example:

Here is what the final setup looks like (youtube video). This video is old and was back when I was using a vp2290b (left monitor) and now I am using a T221 that can take a higher refresh rate (internal refresh of 48Hz vs 41hz) and back then I was using two matrox triple head 2 go in order to go from 2x dual link DVI to 4x single link DVI (what the monitor took). The T221 I have now will natively take dual link DVI.

If you are aware of the limitations (with non XGL) I don't see why you couldn't get working what you want.
Thank you for posting.

Your system looks interesting and maybe even more challenging to setup than what I am trying to do.

Do you have any suggestions as to the steps/process to achieve something like what you have except with 2 video cards (nvidia 570 cards) (I am looking at adding the third card for added computional speed) and 4 identical monitors (each 1920 x 1080)?

Thanking you in advance for your assistance and consideration!!
