I have exactly the same problem! I thought first it to be an aufs 
problem but now I'm quite a sure it is a cloop problem.

Adding 'set -x' to linuxrc gives following last lines:

+ echo /static/insmod -f /cdrom/KNOPPIX/modules/cloop.ko
file=/cdrom/KNOPPIX/KNOPPIX preload=64
+ /static/ash
+ return 0
+ mountit /dev/cloop /KNOPPIX -o ro
+ test -b /dev/cloop
+ options=o ro
+ mount -t iso9660 -o ro /dev/cloop /KNOPPIX

This is with original with linuxrc file from Knoppix 5.1.1.

I'm using 2.6.21-rc2 kernel with aufs source added to the kernel tree 
and compiled as a module (no other patches outside vanilla kernel from 
kernel.org). My configuration and kernel is available from 
http://linux.ilmainen.net/musix/linux-2.6.21-rc2-SMP/ if someone wants 
to try it.

My cloop-src is from Debian unstable (2.0.5). Older version 2.0.4 from 
testing can't be compiled as --added-modules=cloop.
