It's probably possible, though stripping the bloat out of 7.4.2 would probably be easier, though I still wouldn't recommend such drastic alterations to a beginner. On the upside, it was around the 13th of October that Klaus Knopper, the man in charge of Knoppix posted to the Knoppix mailing list that the DVD of 7.6 was complete and that he was working on the CD version, so hopefully it won't be too much longer before we have a release that has eufi support without the added bloat of the DVD.
