is darwin powered by freebsd?

[Ben Kaduk]

Hi all,

I have recently purchased a mac iBook, which is a lot more portable than the
behemoth of a laptop
that I previously used (which runs freebsd), and I have a lot of "powered by
FreeBSD" stickers
lying around. I know that the darwin part of os X is based on FreeBSD, but
is it close enough
to justify putting "powered by FreeBSD" stickers on it? What do you all
think?
