With my Woody installation, the directories you mention did not
exist. Installing libssl0.9.7 (and ssh 3.6.1p1-1) did put files into
/usr/lib/v9. Moving them out of the way as you suggest seems to help
at least a little, though I can still make the connection hang if I
produce a lot of output to the screen, for example with:

	sudo tcpdump -i eth0

When the connection fails, it hangs in different places, for example: 

(client)	debug1: SSH2_MSG_KEXINIT sent
(server)	debug1: kex: server->client aes128-cbc hmac-md5 none
		debug3: preauth child monitor started
		debug3: mm_request_receive entering


(client)	debug1: expecting SSH2_MSG_KEX_DH_GEX_REPLY
(server)	debug1: expecting SSH2_MSG_NEWKEYS

I can't seem to find much on the web on why this might be happening.
