    please understand that I'm only thinking aloud here.

    You should be able to edit (as root/ su -) your /etc/X11/xorg.conf file (make a backup copy of it first). You'll find a chunk of code called the device section. You'll want to end up with two of these, one for each card. Then you'll need to end up with two monitor and two screen sections, to go along with the device section (one for each).

    Then you should (note that word) have a working def for two monitors on two cards (you'll need to have restarted X (Ctrl Alt Backspace kills it, it should then autorestart at the login prompt.).

    I decided to give you a little more help since I'm cool like that. Here's the /etc/X11/xorg.conf file i use for dual display. To use separate cards you will need to define them (including drivers) as necessary in the following file...

    xorg.conf
    Code:
    Section "ServerLayout"
            Identifier     "Multihead layout"
            Screen      0  "Screen0" 0 0
            Screen      1  "Screen1" RightOf "Screen0"
            InputDevice    "Mouse0" "CorePointer"
            InputDevice    "Keyboard0" "CoreKeyboard"
            Option      "Xinerama" "on"
            Option      "Clone" "off"
    EndSection
    
    Section "Monitor"
            Identifier   "Monitor0"
            VendorName   "Monitor Vendor"
            ModelName    "DELL P780"
            HorizSync    30.0 - 85.0
            VertRefresh  48.0 - 120.0
            Option      "dpms"
    EndSection
    
    Section "Monitor"
            Identifier   "Monitor1"
            VendorName   "Monitor Vendor"
            ModelName    "Unknown monitor"
            HorizSync    30.0 - 85.0
            VertRefresh  48.0 - 120.0
            Option      "dpms"
    EndSection
    
    Section "Device"
            Identifier  "Videocard0"
            Driver      "radeon"
            VendorName  "Videocard vendor"
            BoardName   "ATI Radeon 9200"
            Screen 0
    EndSection
    
    Section "Device"
            Identifier  "Videocard1"
            Driver      "radeon"
            VendorName  "Videocard vendor"
            BusID       "PCI:1:0:0"
            BoardName   "ATI Radeon 9200"  
            Screen 1
    EndSection
    
    Section "Screen"
            Identifier "Screen0"
            Device "Videocard0"
            Monitor "Monitor0"
            DefaultDepth 24
            SubSection "Display"
                    Viewport 0 0
                    Depth 24
                    Modes "1024x768" "800x600"
            EndSubSection
            SubSection "Display"
                    Viewport 0 0
                    Depth 24
                    Modes "1024x768" "800x600"
            EndSubSection
    EndSection
    
    Section "Screen"
            Identifier "Screen1"
            Device "Videocard1"
            Monitor "Monitor1"
            DefaultDepth 24
            SubSection "Display"
                    Viewport 0 0
                    Depth 24
                    Modes "1024x768"
            EndSubSection
    EndSection 
    
    Section "DRI"
            Group  0
            Mode   0666
    EndSection
    Don't forget to backup your xorg.conf before editing it incase anything goes haywire.

    Code:
    # cp /etc/X11/xorg.conf  /etc/X11/xorg.conf.bak
    You may need to adjust the HorizSync & VertRefresh according to your monitors otherwise the resolution will be off

    nice one d0p. I wondered how the layout bit was handled.

    have fun
