Let's try (my sshd runs with the -6 switch, remember ?) :

~$ ssh localhost
cgo@localhost's password:

-> works

~$ ssh ip6-localhost
ssh: ip6-localhost: Name or service not known

-> ooops

~$ ssh -6 ip6-localhost
cgo@ip6-localhost's password:

-> works

~$ ssh -6 ::ffff:127.0.0.1  # what you suggested
cgo@::ffff:127.0.0.1's password:

-> works (it also works with my public IP)

~$ ssh -V
SSH Version OpenSSH-1.2.3, protocol version 1.5.
Compiled with SSL.

?

Tell me if I miss the point, but it works for me...
Oh, note that all the IPv6 adresse I have are in my /etc/hosts file
(no AAAAs), and are link scoped.
