I believe if you want to use the synaptics driver, you should be using
an "event" interface.  From my xorg.conf:

        Identifier  "touchpad"
        Driver      "synaptics"
        Option      "Device" "/dev/input/trackpad_evt"
        Option      "Protocol" "event"

I use a special device node because my trackpad and keyboard would
sometimes move around on the generic event nodes.  So I have a udev
rule in 10-local.rules for this:

BUS=="input", KERNEL=="event*", SYSFS{phys}=="isa0060/serio1/input0",
NAME:="input/trackpad_evt", SYMLINK="input/%k"

You can use dmesg to figure out the right setting for SYFS{phys}, or
just use /dev/input/eventX in your xorg.conf.

Of course you'll need to have CONFIG_INPUT_EVDEV in your kernel
configuration to get the event interfaces.
