The issue is that PuTTY does not fall back from its SSH2 attempt to SSH1 
(with password authentication), as is what I specified in my 

Is this what you tried too, or did you use SSH2 (i.e. key 
authentication, instead of password authentication)?

In my case, SSHD is running in debug mode and the debug log clearly 
indicates that PuTTY only tries SSH2 and does not fall back to SSH1, 
whereas on my live box (FreeBSD 5.4 release AMD64, custom kernel), PuTTY 
does fall back to SSH1.

The 'lines' to the new server are about as short as they can be, as I'm 
currently setting the machine up over our local network, so the only 
thing in between the client and server is our router, which does not 
mess with the SSH traffic...

In short: I see no reason why the PuTTY / FreeBSD 6.2 SSH combination 
would _not_ be at fault (especially as other SSH clients do work fine on 
this box, and as PuTTY also works when connecting to other boxes). :P
Contrary to what I was thinking yesterday, I don't think my 
configuration is at fault...

In case in such a situation the password authentication does work fine 
for you, I'd be curious to find out the reason why it doesn't work for 
me (perhaps you could then also post me your sshd_config settings).

As mentioned, there is an easy work around by using a different SSH 
client, but PuTTY is handy for quick d/l-ing when abroad, and not having 
administrator's rights to the machine you're on at that time.
