They key is in your xorg.conf

I guess the important section is in ServerLayout

For example, the below says Screen1 is right of Screen0, and uses 
xinerama to allow the desktop to span both screens.

Section "ServerLayout"
	Identifier     "Default Layout"
	Screen      0  "Screen0" 0 0
	Screen      1  "Screen1" RightOf "Screen0"
	InputDevice    "Mouse0" "CorePointer"
	InputDevice    "Keyboard0" "CoreKeyboard"
	Option	    "Xinerama" "on"
	Option	    "Clone" "off"

Here's an example screen section:

Section "Screen"
	Identifier "Screen1"
	Device     "Videocard1"
	Monitor    "Monitor1"
	DefaultDepth     24
	SubSection "Display"
		Depth     24
		Modes    "1280x1024" "1024x768" "800x600"

It just refers to a videocard and a monitor, and it's what sets the 

A device section says what driver module you're using (and optionally 
the bus - if you have two of the same cards its a good idea to specify that)

Section "Device"
	Identifier  "Videocard1"
	Driver      "tdfx"
	VendorName  "Videocard Vendor"
	BoardName   "Voodoo3 (generic)"
	BusID       "PCI:1:10:0"

The Monitor Section simply states names and the ranges for physical 
characteristics (refresh rates etc) of your monitor.

Section "Monitor"

#	DisplaySize  330	240
	Identifier   "Monitor0"
	VendorName   "Monitor Vendor"
	ModelName    "ViewSonic E70-7"
	HorizSync    30.0 - 70.0
	VertRefresh  50.0 - 120.0
	Option	    "dpms"

Hopefully, combined with the default config you should be able to modify 
it with similar stuff from the above so it works.

Queries welcome.
