problem moving hostkey from ssh version 3.5p1 to 3.8p

[Hari Bhaskaran]

Hi,

I am trying to upgrade from OpenSSH_3.5p1 FreeBSD 4.8 to 
OpenSSH_3.8p1 (Suse 9.1). Although the host rsa and dsa
keys have been copied over from old to new machine, linux ssh
clients (3.8p1) still bring up the new-key alert. ssh clients
from freebsd machines till OpenSSH_3.6.1p1 work fine with 
the setup (without the new key alert)

ssh -vv shows linux clients are looking for type 0 and type 2 key and
freebsd ones are looking for type 0 and type 1 keys

Is this some known incompatibility between ssh 3.6 vs 3.8 or something
between linux vs freebsd?

Any help is appreciated
Thank you.
