Hi,

The hdd installation problem sees:

http://www.knoppix.net/forum/viewtopic.php?t=4709#22739

In briefly, just download:

knx-installer-0.2-1.tar.gz and knx-templates-0.39.tgz

from:
http://debian.tu-bs.de/knoppix/installer/

tar the former and put the latter into the dir ( in ramdisk somewhere), then execute knx-installer.

The plone site created error is due to the CMF-1.4 just as you guessed.
I will downgrade it to 1.3.x
