4.4BSD-lite was the BSD source code after it was "sanitized" as a result
of the AT&T lawsuit.  It was incorporated into FreeBSD 2.0 if history
memory serves me right.

Yes tons.  Very little of the original BSD lite code remains in current
versions from what I have read.

Many FreeBSD mirrors still carry code to FreeBSD 2.0, but that is not
what you want if you just want 4.4BSD-lite.  I think the BSD-lite code
is still available as a tarball to download from various places.  40MB
or so if I recall.  I couldn't find it from a very quick search, but I'm
sure you could find it.  It may even be on ftp.FreeBSD.org if you know
where to look.
