did you edit the correct /etc/passwd and /etc/shadow? the easiest way to do
this is to boot using the rescue system disc, and as root (the default for
mount $ROOT_FS_DEVICE /mnt
$ROOT_FS_DEVICE will be /dev/hda1 or whatever partition the real / is on. once
you're chroot'd into that fs, you're still root but all commands will happen
using that filesystem (and binaries).
hand editting /etc/passwd and /etc/shadow is unecessary and not the safest
thing to do.

suse actually password protects single mode as well... you need to pass
init=/bin/bash to the kernel to get it to drop you into a non-password
protected shell at boot.
