And a reasonable chunk of the kernel still has NetBSD heritage:

ksh$ find xnu -type f -print0 | xargs -0 grep -i netbsd | wc -l
      213
ksh$ find xnu -type f -print0 | xargs -0 grep -i freebsd | wc -l
      361

Mind you, this is Darwin 6.6, aka MacOS X 10.2.6, not quite the latest
and greatest.
