It is possible to use the driver with an ALPS Glidepoint device, if
you are using a 2.6 linux kernel and the ALPS kernel patch. (The
alps.patch file.)

One user reported success with the following parameter settings:

    LeftEdge             = 60
    RightEdge            = 830
    TopEdge              = 70
    BottomEdge           = 650
    FingerLow            = 25
    FingerHigh           = 30
    MaxTapTime           = 180
    MaxTapMove           = 110
    EmulateMidButtonTime = 75
    VertScrollDelta      = 50
    HorizScrollDelta     = 50
    MinSpeed             = 0.2
    MaxSpeed             = 0.5
    AccelFactor          = 0.01
    EdgeMotionSpeed      = 40
    UpDownScrolling      = 1
    TouchpadOff          = 0

Note though that the auto-dev protocol option doesn't work for ALPS
devices, so you have to use the "event" protocol instead and set the
device option to the correct event device, something like this:

Section "InputDevice"
  Driver  	"synaptics"
  Identifier  	"Mouse[1]"
  Option 	"Device"  	"/dev/input/event1"
  Option	"Protocol"	"event"
EndSection
