There is always two sides to a coin. Either you call it knoppix created not enough loop devices or you call it knoppix created one too many loop device/directory.

Furthermore, if you could just extract a copy of /bin/mount from a knoppix 6.2 and test use it on your system ( you could copy it to say /tmp, and then issue command as /tmp/mount), then you will appreciate what I mean:- That extra loop device/directory is not disturbing the system at all with /bin/mount from knoppix 6.2. If you use a newer /bin/mount, yes, it matters.
