Not from me.  :(

While I do use hardware of similar vintage (I really like the IPX and
LX), I just accept the hit.  My ssh implementation supports connection
sharing, meaning I pay the public-key performance penalty only once per
some-long-period (basically, until something crashes or one end is
rebooted).  And, as well as this works for me, it isn't much help for
you, since you want SSL-secured mail, and connection sharing such as I
have my ssh doing doesn't really make sense for that.
