You might want to look at a neat utility called XOSL (eXtended Operating System Loader). XOSL has the ability to boot from a variety of devices and partitions and it can also feed the booting program keystrokes as it boots. So (and this is just theory, I haven't done it with Knoppix although I use it for other similar things) you might be able to let XOSL boot the CD and then feed it the magic cheat codes that you want.

Please post back any results, good or bad.

Here's a link to get you started:
