I remember doing this and got my root password reset. I am not very sure
of what you meant by clear out the root password.
If you left the line en-tact, taking away password info so you have
(in /etc/shadow root:::::::: left, this is how I remember doing it.
Make sure you change the password immediately.
I know you did it this way, but someone new to Linux may take the words
effectively clear the root password as removing the line. This would not
work. Then you could go back to the copy (backup) file you made.
OR you could do something like this:
boot from live CD
mount /dev/hda /mnt/SuSE
chroot /mnt/SuSE /bin/bash
Disclaimer: This is mostly by memory, and some quick look ups
(It just MAY work:)
