Configuring Xorg.conf with Dual Head

Hey all,
I just upgraded to FC5. I did a fresh install from FC4. Sadly, I did not think to back up my xorg.conf file. Now I am trying to setup dual head and I'm running into problems. I remember having similar problems in FC4, with not being able to use the sys-config-display gui, and being forced to manually edit /etc/X11/xorg.conf. I know that both of my video cards are supported, because I used them with FC4(duh) with dual head.

I believe I have everything configured correctly but only ONE display works. I can switch the device priority in my BIOS (either agp or pci). When switching from one device to the other (in BIOS) my machine complains that the xserver cannot start. When viewing the output, it says "no screens found". I then tell it to start with a fresh config and eureka, the server starts. I keep going into this cycle of viewing on one card and trying to configure the other for dual display.

If you all could take a look at my xorg.conf and tell me if I'm missing something, I'd sure appreciate it. Currently in BIOS the device priority is set to AGP (my nvidia card) and then PCI (my ati card). Thanks in advance.

Code:
# Xorg configuration created by system-config-display

# To customise the XKB settings to suit your keyboard, modify the

# If you have a US Microsoft Natural keyboard, you can use:
#	Option	"XkbModel"	"microsoft"
#
# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
#	Option	"XkbLayout"	"de"
# or:
#	Option	"XkbLayout"	"de"
#	Option	"XkbVariant"	"nodeadkeys"
#
# If you'd like to switch the positions of your capslock and
# control keys, use:
#	Option	"XkbOptions"	"ctrl:swapcaps"
