Thanks, that did the trick.  I had to remove
/etc/modprobe.d/psmouse.modprobe to get the ALPS GlidePoint to show up as
itself in /proc/bus/input/devices rather than as a generic PS/2 mouse.  Then
I inserted this stuff into my /etc/X11/xorg.conf:

Section "InputDevice"
Identifier "ALPS"
Driver "synaptics"
Option "AlwaysCore"
Option "Device" "/dev/input/event3"
Option "Protocol" "event"
Option "LeftEdge" "120"
Option "RightEdge" "830"
Option "TopEdge" "120"
Option "BottomEdge" "650"
Option "FingerLow" "14"
Option "FingerHigh" "15"
Option "MaxTapTime" "0"  # was 180.  Set to 0 to disable tap-to-click
Option "MaxTapMove" "110"
Option "ClickTime" "0"
Option "EmulateMidButtonTime" "75"
Option "VertScrollDelta" "10"
Option "HorizScrollDelta" "0"
Option "MinSpeed" "0.45"
Option "MaxSpeed" "0.75"
Option "AccelFactor" "0.020"
Option "EdgeMotionMinSpeed" "200"
Option "EdgeMotionMaxSpeed" "200"
Option "UpDownScrolling" "1"
Option "CircularScrolling" "0"
Option "CircScrollDelta" "0.1"
Option "CircScrollTrigger" "2"
Option "SHMConfig" "true"
EndSection


Section "ServerLayout"
    Identifier    "Default Layout"
    Screen        "Default Screen"
    InputDevice    "Generic Keyboard"
#    InputDevice    "Configured Mouse"
    InputDevice    "ALPS"
EndSection

Even without "Configured Mouse" it still detects my USB mouse.

One thing that's a little strange is that sometimes the touchpad shows up on
event2 and sometimes on event3.  Not sure how to deal with that...
