And it can't work because .. login isn't suid root. Without suid root
you can't do this. Also usualy /etc/pam.d/login uses pam_securetty PAM
module which forces login for root user only from tty's listed
in /etc/securetty. So in case typical PAMified login adding suid root
also can't help.

Use su or sudo for gain root login.

This is not a bug and IMO this case can be closed.
