I have one of these mice and I love it. Instead of a scrollwheel, it has a little "joystick" just behind the middle button. And what's more, it lights up blue!

Anyway, I keep having to set up my xorg.conf file for it, and I always have to puzzle out the correct configuration. (Yes my hard drive failed and I'm having to rebuild my whole machine.) Well, here it is:

Section "InputDevice"
        Identifier      "Configured Mouse"
        Driver          "mouse"
        Option          "CorePointer"
        Option          "Device"                "/dev/input/mice"
        Option          "Protocol"              "ExplorerPS/2"
        Option          "Emulate3Buttons"       "true"

The mouse is plugged into the USB port. ZAxisMapping doesn't seem to be necessary, or to do anything useful.

The mouse "wheel" still scrolls a little too fast for my liking. If you are brave, you could try this patch to Linux's mousedev module.
