Default Re: 1.0-9746 dual screen problem

I tried what you suggested but it doesn't work (cf. below).

I want two X servers, one on each card of my 7950gx2.

lspci gives:
04:00.0 3D controller: nVidia Corporation Unknown device 0294 (rev a1)
05:00.0 VGA compatible controller: nVidia Corporation Unknown device 0294 (rev a1)
My main X server is launched on the PCI:5:0:0 and I created a "fake layout" for the second server:
Section "ServerLayout"
   Identifier     "Layout01fake"
   Screen         "Screen01fake" 0 0
   InputDevice  "Fake Keyboard"
   InputDevice  "Fake Mouse"

Section "InputDevice"
 Identifier     "Fake Mouse"
 Driver "void"
 Option "CorePointer"

Section "InputDevice"
 Identifier     "Fake Keyboard"
 Driver         "void"
 Option "CoreKeyboard"

Section "Device"
    Identifier     "Device01"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
BusID "PCI:4:0:0"
Option "NoInt10" "Yes"

Section "Screen"
    Identifier     "Screen01fake"
    Device         "Device01"
    Monitor        "Monitor0"
    DefaultDepth    24
    SubSection     "Display"
        Depth       24
        Modes      "1600x1200" "1280x1024" "1024x768" "800x600" "640x480"
and when I run
export DISPLAY=:0.1
sudo X -novtswitch -sharevts -layout Layout01fake -auth /var/lib/gdm/:1.Xauth vt7 :1
I got the following error:
X Window System Version 7.1.1

X Protocol Version 11, Revision 0, Release 7.1.1

        Before reporting problems, check
        to make sure that you have the latest version.

Fatal server error:
AddScreen/ScreenInit failed for driver 0
If I use another pci-express card and use it that way it works but I can't get the 2 cards in the 7950gx2 to work.

Any suggestion ?

Thank you for your help.
