How about telling us what version/distro of Linux you're using??
And from your first post, telnet isn't showing up in nmap, so it's no surprise you can't connect to it. A Google search turns up lots:
Are you sure your telnet client can use IPv6? There's a program called telnet6 for a reason. Also, if you're going with IPv6, why bother with telnet, which is old, unsafe, and unused (mostly) these days. That's why SSH is usually used.
You may also need to add "flags = IPv6" in the service entry in /etc/xinetd.d.
