I'm not sure if this is the correct way to change, or disable a root
password.. There is a corresponding entry in /etc/shadow which actually
holds the password.

An easy way to reset the password properly - one I've not tried mind,
would be to boot off your knoppix cd, mount /dev/hda3 somewhere
then, as root from knoppix (via sudo or su), issue
"chroot /where/I/mounted/hda3"

You should now be the "root" user in your normal system, give or take.
You should be able to change the root password with the normal "passwd"
command.
