That sounds like an extremely cool patch! I probably will add it to Nmap.
When you send it to me, CC the list so they can look it over and try it
out. Hopefully they will send any problems or suggestions to you and I.

It does for me:
amy~#nmap -O -sS 216.218.218.233
[ . . . ]
Remote operating system guess: Solaris 2.6 - 2.7
amy~#nmap -O -sS 207.69.138.68
[ . . . ]
Remote operating system guess: FreeBSD 2.2.1 - 4.0
You aren't scanning through a some sort of NAT or IP masquerading device,
are you? Those can corrupt the fingerprints. If you have a real IP
address with no strange network obstructions between you and the
www.insecure.org machines, run nmap with -d and send me the fingerprints
it produces.
Cheers,
Fyodor
