Fedora Users — FC3, Sharp MM20, Synaptics touch pad

I've just done a clean install of FC3 on a Sharp MM20, and I'm hitting a wall trying to get the touchpad working. External USB mouse works fine. I have the latest synaptics driver compiled and installed. Xorg.0.log shows:

(II) Synaptics touchpad driver version 0.13.6
Touchpad no synaptics event device found (checked 3 nodes)
(**) Option "Device" "/dev/psaux"
(EE) xf86OpenSerial: Cannot open device /dev/psaux
       No such file or directory.
Synaptics driver unable to open device
(EE) PreInit failed for input device "Touchpad"
(II) UnloadModule: "synaptics"

There is indeed no /dev/psaux, though I have made it twice with MAKEDEV. It disappears a each reboot. Also I note that the driver seems to be saying that it does not see the touchpad.

My xorg.conf is below. If I use the two commented lines in the server layout section te replace the two following lines, the system hangs on boot. Can anyone help?

Frank.

# To customise the XKB settings to suit your keyboard, modify the
# lines below (which are the defaults).  For example, for a non-U.S.

#       Option  "XkbModel"      "pc102"
# If you have a US Microsoft Natural keyboard, you can use:
#       Option  "XkbModel"      "microsoft"
#
# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
#       Option  "XkbLayout"     "de"
# or:
#       Option  "XkbLayout"     "de"
#       Option  "XkbVariant"    "nodeadkeys"

# If you'd like to switch the positions of your capslock and

# Or if you just want both to be control, use:
#       Option  "XkbOptions"    "ctrl:nocaps"
