I was able to get this working at one point, however it was extremely unstable... my system would hardlock all the time. I'm not entirely sure what the problem was, and I've never been able to get a response or any type of help no matter how many times I ask. Either way, here's the XF86Config I was using, if it's any help to either of you. If anybody knows more about this, please let me know. I'm currently only using one video card/monitor, and the other is just sitting there uselessly.
