I gather you mean this paper:

http://www.caida.org/outreach/papers/2005/fingerprinting/

It's an interesting read.

As to how vulnerable FreeBSD is to this I do not know nor do I know if
we should bother to do anything about it.  What, in particular are you
worried about here?  Also, if you consider this a security issue you
should probably also include the security team in this discussion.

Later,
George
