xorg.conf Configuration with Dual ATI Cards

[bensun13]

I just installed a second ATI card on my Dell Optiplex 760. The original card is ATI RV620 LE [Radeon HD 3450] with a dual header. The card worked out of the box and I installed the proprietary fglrx driver for it. Now, I've added an additional card (ATI RV516 [Radeon X1300/X1550 Series]) and am trying to configure it to run a third monitor. I've tried to run both proprietary (fglrx) and open source (radeon) drive on both cards. One thing I noticed is that when I set both cards to use fglrx in my xorg.conf aticonfig seg faults. Ubuntu doesn't seem to recognize the third monitor and merely displays the Ubuntu logo on it. Anybody know what I am doing wrong? Below is the xorg.conf:
