[lug] Pointer goes nuts

[David]

Thank you Dan, thank you Ferdinand.  It was very helpful to know that
xev was reporting differently on Dan's machine.  If was even more
helpful to have it pointed out that I might be modifying the wrong
XF86Config.  Although the two files do have a different format:

Section "Pointer"
    Protocol        "IMPS/2"
    Device          "/dev/mouse"
    Resolution      100
    Buttons         5
    ZAxisMapping    4 5

Section "InputDevice"
	Identifier  "Mouse0"
	Driver      "mouse"
	Option      "Device" "/dev/mouse"
	Option      "Protocol" "IMPS/2"
	Option      "Emulate3Buttons" "off"
	Option      "ZAxisMapping" "4 5"
EndSection

I had to restart X as well.

I really hate using a mouse at all, I'm a keyboard person.  But the
wheel takes out quite a lot of the point-and-click hassle.
