OK, this is going in the right direction.  I created a file called
/etc/udev/rules.d/40-personal.rules with the following contents:

# touchpad
BUS=3D=3D"serio",SYSFS{description}=3D=3D"i8042 Aux-3 Port",
KERNEL=3D=3D"event?",SYMLINK=3D"input/touchpad"

# USB mouse
BUS=3D=3D"usb",KERNEL=3D=3D"mouse?", SYMLINK=3D"input/usb_mouse"


and changed the relevant lines of /etc/X11/xorg.conf to

     Option          "Device"                "/dev/input/usb_mouse"

and

     Option "Device" "/dev/input/touchpad"



Now when I reboot, the USB mouse works but the touchpad does nothing.  If I
then do ctrl-alt-backspace to restart X, it all works perfectly with no
tap-to-click.  I can live with this, though I'd be curious if there's a way
to make it work without this little kludge.
