Laptop Mouse pad jumps at boot - Ubuntu

Alright, so here's my issue.

When I boot my computer (I run Ubuntu 7.10 on an old Dell Latitude with Xfce), my mouse jumps randomly to the usually the left side of the screen. The weird thing is, when I plug in a corded mouse, everything works fine. Then, when I unplug the mouse, my touch pad works fine as well.

I figured at that point I could just find some code to run at boot to "reset" the mouse, but that didn't work. I ended up running this code:

$ synclient TouchpadOff=1
$ synclient TouchpadOff=0

The nub is disabled, and the contents of xorg.conf is as follows:

Section "InputDevice"
Identifier "Configured Mouse"
Driver "mouse"
Option "CorePointer"
Option "Device" "/dev/input/mice"
Option "Protocol" "ImPS/2"
Option "ZAxisMapping" "4 5"
Option "Emulate3Buttons" "true"

Section "InputDevice"
Identifier "Synaptics Touchpad"
Driver "synaptics"
Option "SendCoreEvents" "true"
Option "Device" "/dev/psaux"
Option "Protocol" "auto-dev"
Option "HorizEdgeScroll" "0"
Option "SHMConfig" "on".

All help is welcome!

Is the pointer in the keyboard disconnected, or just disabled in software? I had to completely disconnect mine, it was causing problems, though some say you can put a piece of anti-static bag under the keyboard to block whatever is interfering with it.
