I got a dual moniter display working using two nvidia cards. Both are using the nvidia kernel module and run great. One moniter is a 1600x1400 lcd and the other is a 1248x1024 crt. I've written a small tutorial on my site [http://www.socklabs.com/post/2/263
]. Feel free to ask any questions or write comments. By the way this is also a small tutorial on getting nvidia display drivers working on fedora core 2. I've seen some people having issues with that.
