Configuring Panther to run an Agfa Arcus II scanner

Question

Greetings!
For reasons I won't bore you with, I have to configure an Agfa Arcus II flatbed scanner to run under 10.3. Agfa stopped actively supporting its scanners several years ago, but they still maintain support info on their web site and do provide information on how to get the scanner up and running.
However, doing so requires two original system files from a system running 10.2.8. I have no access to such a system (or to the software to set up the recommended partition) and was wondering if any of you might.
For the benefit of others who may be facing this or a similar problem, I've included part of Agfa's instructions below. (To read the entire procedure, go to www.agfa.com and follow the links on the support page.)
Thanks in advance.
How to make FotoLook 3.6 work on Mac OS 10.3
In order to make FotoLook 3.6 work on OS 10.3, you need to replace some sytem files by older system files from OS 10.2.8.
This action is only recommended if you really want to use your scanner on 10.3. A better and safer solution is to keep a partition with 10.2.x and use your scanner on that partition.
First make a backup of your system folder before proceeding. Modifications on system/library can destabilize your system.
If you are familiar with Terminal, make yourself root user and copy the following two files from an old 10.2.8 into the system folder of 10.3

IOSCSIParallelFamily.kext
Location: System/Library/Extensions

Hi KET,
Kext swapping for compatability with scsi is not a real problem as long as you understand that it may change the way that those kext files interact with other devices. If you are only using the Arcus with scsi I don't think that you will find any problems.
As for getting the files into the system it would have to be done while booted onto another partition or hard drive. You could also boot target mode on another mac and do the swap. I have tried swapping kext files on an active/booted system and it caused problems. I'm sure that there is a way to do it in Terminal but I don't know what it is.
As for the files themselves, I have them on an old computer in the garage and I thinkd it still boots. I would have to network it to my current mac to get the files. Alternatively, you might be able to use Pacifist to get the files off of a combo update from Apple.
