Aha, I did not know that.  Thank you. According to:
http://lists.freebsd.org/pipermail/freebsd-questions/2006-March/117134.html

sysctl -a 

will give you the same information on Freebsd systems.  Just in case
anybody cares because setting the -march settings looks to accomplish
the same thing, and is a lot easier.
