Other things that got me that you might want to look out for. Sorry if some of this seems obvious.

1) It's probably something I did, but if knoppix doesn't have permissions to the /etc/skel/.kde items they won't get copied on boot and you won't see them.

All items should be owner: root, group: root, permissions: rwxr-xr-x. These dirs get copied to the /home/knoppix dir during all that boot time magic. It looks like they get chgrp'ed and chown'ed to knoppix at that time.

You can do this in a root shell by "chmod -R 755 /etc/skel/.kde/"

2) KDE menu items are files such as Mutt.desktop. You can view and modify their contents with vi.

I noticed that sometimes menu items would simply disappear after modifying them in KMenuEditor. What happens is that a line that reads:

Hidden=false

gets removed somehow. Manually putting that back into the .desktop file brought the item back.

Thanks,
