If I use 

Section "Device"
        Identifier  "Videocard0"
	BusID       "PCI:2:2:0"
        Driver      "ati"
        VendorName  "Radeon Mobility 9000"
        BusID       "PCI:2:2:0"
	Screen 0

Section "Device"
        Identifier  "Videocard1"
        Driver      "ati"
        VendorName  "Radeon Mobility 9000"
        BusID       "PCI:2:2:0"
	Screen 1

I still only get the display duped in both monitors.
I tried without
Screen 0
Screen 1
specified in device section as well, still no joy. Screen 0 and Screen 1 are
always duplicates.

Also saw a similar type thing when testing with a Matrox G550, could only
get duplicate
screens, but it only showed one BusID.

I am using the same basic configs outside of the device section for
Videocards that works up to a four head setup.
But those where using the older Colorgraphics cards based on cirrus.

Anything else I may be doing wrong?
