pad buttons don't send anything

Hello,

I have a 6x8 USB Graphire, but I'm unable to use the buttons/scroll-wheel on 
the pad itself.  Even xev doesn't recognize events.  Is there a way to map 
those keys to something?

Below are my relevant sections in xorg.conf.  Does the lack 
of "SendCoreEvents" equate to lack of buttons?  I can understand why the pad 
wouldn't send positioning, but can it send buttons?

Section "InputDevice"
  Driver        "wacom"
  Identifier    "stylus"
  Option        "Device" "/dev/input/event2"
  Option        "Type" "stylus"
  Option        "USB" "on"
EndSection

Section "InputDevice"
  Driver        "wacom"
  Identifier    "eraser"
  Option        "Device" "/dev/input/event2"
  Option        "Type" "eraser"
  Option        "USB" "on"
EndSection

Section "InputDevice"
  Driver        "wacom"
  Identifier    "cursor"
  Option        "Device" "/dev/input/event2"
  Option        "Type" "cursor"
  Option        "USB" "on"
  Option        "Speed" "3.0"
EndSection

Section "InputDevice"
  Driver        "wacom"
  Identifier    "pad"
  Option        "Device" "/dev/input/event2"
  Option        "Type" "pad"
  Option        "USB" "on"
EndSection


Section "ServerLayout"
  Identifier   "Layout[all]"
  InputDevice  "Keyboard[0]" "CoreKeyboard"
  InputDevice  "Mouse[1]" "CorePointer"
  InputDevice  "stylus" "SendCoreEvents"
  InputDevice  "eraser" "SendCoreEvents"
  InputDevice  "cursor" "SendCoreEvents"
  InputDevice  "pad"
  Option       "Clone" "off"
  Option       "Xinerama" "off"
  Screen       "Screen[0]"
EndSection

Thanks,
Jeff
