Question on setup of xorg.conf for laptop

My laptop has a Synaptics touchpad and also has a plug for an external
mouse.  I boot into run level 3.  The touchpad works when I boot.  Once
I've booted and started X, I can plug in the mouse and both it and the
touchpad can control the pointer.  However, if I boot with the mouse
plugged in, X crashes when I try to start it.  How can I boot with the
mouse plugged in and have the mouse and touchpad both work?

I've attached the relevant part of my xorg.conf file below.
