Remaster the CD. A script would by necessity have to download it from somewhere or access it from a permanent medium like a usb pen or hard drive persistent home. And you can't very well download a NIC driver in the script because well, you'd need a NIC driver to do so.

PS- I will add that driver to my remaster and post back once its available for download... unfortunately, my custom version of knoppix is somewhat imperfect if you like using KDE.
