If they've released it all as open-source, then it must not be based on original BSD code and therefore doesn't require licensing.  My bad.

Found this with a quick Google search (more complete):

http://osxbook.com/book/bonus/ancient/whatismacosx/arch_xnu.html

In the "BSD" section it says:  "XNU's BSD component uses FreeBSD as the primary reference codebase (although some code might be traced to other BSDs). Darwin 7.x (Mac OS X 10.3.x) uses FreeBSD 5.x."
