Hi Rob.

What desktop GUI are these machines using?

Is there some way you get each machine to use it's own
custom xorg.conf file, that you can tweak for each
particular machine?

I use this this in my PC running Centos 5.8 32 bit,
and XFCE desktop, to give me a tall virtual screen that I
can scroll around vertically:

# Xorg configuration created by system-config-display

InputDevice "Keyboard0" "CoreKeyboard"
