I have a Thinkpad T42p w/ SUSE9.3 and w/USB mouse and Touchpad running.
As Desktopmanager I use KDE.
It worked just fine after the first install.

The parts of my configuration file related to this: /etc/X11/xorg.conf :

Section "InputDevice"
  Driver       "synaptics"
  Identifier   "Mouse[1]"
  Option       "Device" "/dev/input/mice"
  Option       "Emulate3Buttons" "on"
  Option       "InputFashion" "Mouse"
  Option       "Name" "Synaptics;Touchpad"
  Option       "Protocol" "explorerps/2"
  Option       "SHMConfig" "on"
  Option       "Vendor" "Sysp"
  Option       "ZAxisMapping" "4 5"

Section "InputDevice"
  Driver       "mouse"
  Identifier   "Mouse[3]"
  Option       "Buttons" "5"
  Option       "Device" "/dev/input/mice"
  Option       "Name" "Logitech Optical USB Mouse"
  Option       "Protocol" "explorerps/2"
  Option       "Vendor" "Sysp"
  Option       "ZAxisMapping" "4 5"


Section "ServerLayout"
  Identifier   "Layout[all]"
  InputDevice  "Keyboard[0]" "CoreKeyboard"
  InputDevice  "Mouse[1]" "CorePointer"
  InputDevice  "Mouse[3]" "SendCoreEvents"
  Option       "Clone" "off"
  Option       "Xinerama" "off"
  Screen       "Screen[0]"

The modules should be loaded correctly 

tail -f /var/log/messages shows me that the mouse is detected as follows:

Sep 27 17:01:25 linux kernel: usb 2-2: new low speed USB device using uhci_hcd 
and address 5
Sep 27 17:01:25 linux kernel: input: USB HID v1.10 Mouse [Logitech Optical USB 
Mouse] on usb-0000:00:1d.1-2

If you want to see my lsmod output to compare with your list of modules, let 
me know. I can send it to you, but usually all the modules necessary for USB 
should have been loaded without the need to load them manually.

Kind regards,
