Same here with kernel 2.6.14.2, X.org 6.9RC, udev 0.070:

(II) LoadModule: "synaptics"
(II) Loading /usr/X11R6/lib/modules/input/synaptics_drv.o
(II) Module synaptics: vendor="The XFree86 Project"
        compiled for 4.2.0, module version = 1.0.0
        Module class: XFree86 XInput Driver
        ABI class: XFree86 XInput driver, version 0.3
[...]
(II) Synaptics touchpad driver version 0.13.6
Custom TouchPad no synaptics event device found (checked 1 nodes)
(**) Option "Device" "/dev/psaux"
(**) Option "SHMConfig" "on"
(**) Option "LeftEdge" "1700"
(**) Option "RightEdge" "5300"
(**) Option "TopEdge" "1700"
(**) Option "BottomEdge" "4200"
(**) Option "FingerLow" "25"
(**) Option "FingerHigh" "30"
(**) Option "MaxTapTime" "180"
(**) Option "MaxTapMove" "220"
(**) Option "VertScrollDelta" "100"
(**) Option "HorizScrollDelta" "10"
Query no Synaptics: 6003C8
(EE) Custom TouchPad no synaptics touchpad detected and no repeater device
(EE) Custom TouchPad Unable to query/initialize Synaptics hardware.
(EE) PreInit failed for input device "Custom TouchPad"
(II) UnloadModule: "synaptics"


So this isn't directly related to kernel version, nor Xorg version, nor
udev version:

$ cat /proc/bus/input/devices 
[...]
I: Bus=0011 Vendor=0002 Product=0007 Version=0000
N: Name="SynPS/2 Synaptics TouchPad"
P: Phys=isa0060/serio1/input0
H: Handlers=mouse0 
B: EV=b 
B: KEY=6420 0 70000 0 0 0 0 0 0 0 0 
B: ABS=11000003 

and kernel log says:

/var/log/syslog.0:Dec 23 00:40:59 atto kernel: input: SynPS/2 Synaptics TouchPad on isa0060/serio1

What could be going wrong ???
