First, you'll need a precise definition of what you mean by "free memory".

Add the "-H" flag to get that value more precise. I suspect, however,
that precision isn't really the right term for what you're after.
Have you seen:
http://www.freebsd.org/doc/en_US.ISO8859-1/books/faq/misc.html#TOP-FREEMEM
and
http://www.freebsd.org/doc/en_US.ISO8859-1/books/faq/admin.html#FREE-MEMORY-AMOUNT
by any chance?
