If you are using a linux 2.6 kernel, you can use udev (which will replace 
devfs, now marked as obsolete). I don't know if your distro already uses it, 
but with gentoo I'm using it from linux-2.6.0-beta1.

One of the goal of udev is to create persistent devices. You can create a 
simple udev rule that let you assign the same device for your pilot.

You can find various howto on the net that guide you on how to configure it.
for example this:
http://www.reactivated.net/udevrules.php

Of course, if you don't want to use udev, you can create a simple hotplug 
script that symlink the created device with a fixed one. But udev (under 
linux) is the right way to do this kind of things.

Bye!
