In the end Jason had the fix all along!
On Vista 64 you need to comment the ::1 line in the Windows host file (and I
presume in the /etc/hosts file in cygwin if its different) to get sshd allowing
connections.

There does seem to be a minor incompatibility for the lookup with vista and
cygwin. I can't do ssh localhost even with the workaround in place. However ssh
192.168.y.x works correctly from Putty and from cygwin bash.

It would be nice if this note could be put in the FAQ/manual for now so that
everyone with this problem knows the workaround, at least until a better fix is
found.
