Okay, so I hacked together a driver which is able to read at least the
newest Knoppix image (from 3.6EN).

Only problem: When you start it with

qemu -hda /cdrom/KNOPPIX/KNOPPIX \
  -kernel /cdrom/boot/isolinux/linux24 \
  -initrd /cdrom/boot/isolinux/minirt24.gz \
  -append root=/dev/hda

Knoppix believes it runs from the HD (installed version) and does not
recreate /etc/fstab, and then just stops.

Any Knoppix hackers out there? Maybe one can trick Knoppix into recreating
all these files nontheless?
