I'm in the same boat you are, RHEL 4 WS fresh install. Here is my config:
Code:
Section "InputDevice"
Identifier "Mouse0"
Driver "mouse"
Option "Protocol" "ExplorerPS/2"
Option "Device" "/dev/input/mice"
Option "ZAxisMapping" "4 5"
Option "Buttons" "5"
EndSection
I tried using the event driver, but I don't think RHEL 4 has it.
