Looks like there are multiple different versions of CDROM/DVDs which do different things in the syslinux.cfg/isolinux.cfg, with different parameters and cheatcodes.

The actual work of ejecting the cdrom is in /etc/init.d/knoppix-halt, so you should check that it's intact. Assuming that's intact, then you should check if your syslinux.cfg/isolinux.cfg contains things like 'noeject'/'noprompt' which will inhibit the eject of cdrom and its prompting.

You will be surprised that if I tell you the copy of KNOPPIX 6.2 CDROM which I have does eject the cdrom which shutting down.
