[luau] Mouse Wheel in Red Hat 7.3

[W. Wayne Liauh]

Thanks.  Below is the pertinent section that I copy from Mandrake 8.2:
Section "InputDevice"

   Identifier  "Mouse1"
   Driver      "mouse"
   Option "Protocol"    "IMPS/2"
   Option "Device"      "/dev/mouse"
   Option "ZAxisMapping" "4 5"

# ChordMiddle is an option for some 3-button Logitech mice

#    Option "ChordMiddle"

EndSection


(Mandrake 8.2 has no problem whatsoever detecting my Logitech optical 
wheel moust.
But Red Hat seems to run KDE a little bit faster.)
