Just retried on an AIX 5.2 ML1 box with 3.6.1p1 and reproduced the
problem with both authorized key and password authentication.

Running on AIX 4.3.3 ML11, 5.1 ML3 and ML4, and 5.2 ML1; built on 4.3.3
ML11, 5.1 ML3 and 5.2 ML1.  Protocol 2 in all cases, with clients from
the same OpenSSH versions on AIX 5.1 ML3 and RedHat 9, as well as
SecureCRT 4.0.  Just gave it a try with protocol 1 on a 5.2 ML1 box
(from 3.6.1p1 client on 5.1 ML3) and it seems to behave the same way
(though I haven't dug into the code path yet to see if it's really the
same thing, it definitely hangs).
