Look at
    http://www.apple.com/macosx/technologies/darwin.html

This includes the following:

    At its core, Darwin uses BSD. If you're a hardcore
    geek, you'll like having a full command set available to
    you from the terminal.
    Developers will appreciate how easy it is to port existing UNIX applications
    to Mac OS X. Plus, Mac OS X incorporates the time-tested
    BSD networking stack, the backbone of most TCP/IP implementations
    on the Internet today.

    Best of all, Darwin is distributed under Apple's Open Source
    license, so engineers around the world can help Apple make Mac
    OS X the best operating system on the

This points to http://www.freebsd.org/
which includes:

    FreeBSD is an advanced operating system
    for Intel ia32 compatible, DEC Alpha, and
    PC-98 architectures. It is derived from BSD
    UNIX, the version of UNIX developed at the
    University of California, Berkeley. It is
    developed and maintained by a large team
    of individuals. Additional platforms are in
    various stages of development.

That points to
    http://www.freebsd.org/platforms/index.html

The ppc project seems to have some way to go. Anyhow it's
clear that the Mac Os X can't be be ONLY freeBSD.

I think OpenBSD runs on ppc however.
