IFAICR, its been a part of X11 for a long time.  X11R3?

I've been fartzing with with my X11 after my FC5->F8 upgrade, and my
Logitech MX1000 mouse isn't working right yet.  The old "InputDevice"
section in my old xorg.conf produces a NULL, no core pointer error.
Funny, it used to work OK under FC5.

nope, its just not common knowledge, because most 2 and 3 button mice
just work "out of the box".

IIRC, ZAxisMapping is usually used for your scroll wheel, to map it from
the "button events" generated by the mouse driver.  X and Y axis stuff
is usually the mouse movement.

Not very well documented black magic.  B^)
