Sure.  To mount a 200 MB swap-backed memory filesystem on
/tmp, add this lie to /etc/fstab:

md   /tmp   mfs   rw,async,nosuid,-s200m,-m0   0   0

You mean a diskless setup?  I think there's a detailed
description of diskless setups in the FreeBSD Handbook.
You might also want to look at the diskless(8) manpage.

PS:  Such questions are more appropriate for the freebsd-
questions list.  They're not really "hacker" questions.
