Neat!  I just ran it from the command line and it identifies things as 
follows:

Left mouse button: Button 1
Right mouse button: Button 3
Middle mouse button: Button 2
Scroll wheel forward: Button 4
Scroll wheel backward: Button 5
Tilt wheel left: Button 6
Tilt wheel right: Button 7
Down arrow button: Button 8
up arrow button: Button 9

What a simple and interesting tool.  So how can I use this information?

The relevant part of my xorg.conf file is this:

Section "InputDevice"
         Identifier  "VX Nano"
         Driver      "evdev"
         Option      "Name" "Logitech USB Receiver"
         Option      "Protocol" "evdev"
         Option      "Buttons" "9"
         Option      "SendCoreEvents"
         Option      "HWHEELRelativeAxisButtons" "7 6"
         Option      "Emulate3Buttons" "false"
EndSection

I got this configuration from some web site mainly focusing on the EEE 
PC, but had mention of my mouse.  This basically works.  Perhaps it's 
just the game doesn't read beyond a certain number of buttons on a mouse?
