It does give a sample Section "InputDevice" which has this set.

I have been using mine on 7.0 for a while.
/etc/X11/xorg.conf
Section "InputDevice"
        Identifier      "Synaptics_Touchpad"
        Driver          "synaptics"

        Option          "Device"                "/dev/psm0"
        Option          "Protocol"              "psm"
        Option          "SHMConfig"             "on"
EndSection

With this I can use x11/gsynaptics which uses synclient fine. I also have
        InputDevice    "Mouse0" "CorePointer"
        InputDevice    "Synaptics_Touchpad" "SendCoreEvents"
        InputDevice    "Keyboard0" "CoreKeyboard"



and Section "InputDevice"
        Identifier  "Mouse0"
        Driver      "mouse"
        Option      "Protocol" "Auto"
        Option      "Device" "/dev/sysmouse"
        Option      "ZAxisMapping" "4 5 6 7"
EndSection

so I can have both the synaptic pad and the usb mouse active at the same
time (saves reconfiguring when I have an external mouse plugged in.)
