actually, you don't need the patch for most installation as the reason for it is that you can add lots of boot prompt parameters but if it is not that much, the default (256 byte) should be enough, knoppix use 512.

I no longer boot into KNOPPIX so I don't have that at hand, just ask someone to post it, it is really very simple.

You can also boot into the CD and copy or have a look at it. no need to do any reinstallation.
