In /etc/X11/xorg.conf find the appropriate screen section ...

Look for something like the following :

Section "Screen"
    Identifier  "Screen name"
    Device      "Some device name"
    Monitor     "Some monitor name"
    DefaultDepth 24

    Subsection "Display"
        Depth       24
        Modes       "1280x800" "1024x768" "800x600" "640x480"
        ViewPort    0 0
        Virtual     1600 1200

The "Virtual" line is the one of interest - change the numbers to something bigger than the resoltion (Mode).  Restart
X and you should have your giant desktop.
