Ok, I found the bug. It was in the ipv6 hash function where I made
a mistake with the hashmask.

The updated patch is here:

 http://www.nrg4u.com/freebsd/tcphostcache+ipfastforward-20031112.patch

Could you try again please?

I have organized a second IPv6 capable machine (OpenBSD) for testing
and I was able to ssh from my development machine to the OpenBSD via
IPv6 tcp connection. I hope the last update has ironed out all ip6
bugs now.
