Just found that Subversion 1.7 (TortoiseSVN-1.7rc1) with serf-1.0.0
supports negotiation.

And it just works!
Serf even does not have the restriction of doing negotiate in TLS...
So much easier to look at using wireshark.

BTW: neon in this release does not even request ticket for target
server... And fails for unknown GSS error.
svn: E170001: OPTIONS of
'': authorization
failed: Could not authenticate to server: GSSAPI authentication error:

So we have even further regression in neon, and huge success for serf.
