I can't quite follow your bug report, but from the looks of this config file:
https://bugzilla.redhat.com/bugzilla/attachment.cgi?id=109851
it's a configuration problem.

the first error is right here:
	Screen      0  "Screen0" LeftOf "Screen1"
	Screen      1  "Screen1" 0 0

you can't have negative screen coordinates.  try something like this:
	Screen      0  "Screen0" 0 0
	Screen      1  "Screen1" RightOf "Screen0"

Next you will need to specify the busids of each video device.  eg:
	BusID       "PCI:1:0:0"
 for your add in card and:
	BusID       "PCI:0:2:0"
for the intel.  double check your x log or lspci to make sure you get
the ids right.

and finally, if you wants modes greater than 800x600, you will need to
specify them so add larger modes to the modes line in your screen
sections:
		Modes    "1024x768" "800x600" "640x480"

Give that a try and you should make some progess.
