You should try configuring all 3 and find out ;)  If you keep the original
file in the same directory, the worst that can happen is your X server won't
start, and you end up logging into a console and moving the original back
into place.

As for which file to use from dev, the best way to do this, I think, is to
create a file in /etc/udev/rules.d/, and then write your own udev rule that
creates a unique symlink to the correct file whenever you plug in the

For example, I have a Logitech MX500, if I want to use it with evdev, I need
to point to the right /dev/input/eventX file, so I have a line in
/etc/udev/rules.d/99-custom.rules like so:

KERNEL=="event*" ACTION=="add" SYSFS{manufacturer}=="Logitech"
SYSFS{product}=="USB-PS/2 Optical Mouse" RUN+="/usr/sbin/logitech_applet -d
-s 800" SYMLINK="input/mx500"

The == are checks, the = are assignments.  For info on how to write your own
rules, I recommend looking at this

I'm also using Ubuntu 6.06, by the way, that and Gentoo.
