The patch is available here:
http://people.freebsd.org/~andre/tcp_auto_sndbuf-20061116.diff
Any testers, especially with busy FTP servers, are very welcome.
A RELENG_6 version (for FreeBSD 6.x) of the patch is here:

Just apply this patch and recompile your kernel. It is activated by default.
Be aware that all socket buffer sizing events get logged to syslog under
LOG_DEBUG. This may affect overall system performance and you may want to
disable logging to disk of this in syslogd.conf.
