On CURRENT:

man vnconfig
man vn

I mount a swap backed fs (which I what I suspect you want) with:

vnconfig -e -s labels -S ${vn_tmp_size} ${vn_tmp_device} && \
disklabel -r -w ${vn_tmp_device} auto && \
newfs /dev/${vn_tmp_device}c > /dev/null  && \
mount -o nosuid -o nodev /dev/${vn_tmp_device}c /tmp && \
chmod 1777 /tmp

N.B. I don't reserve the blocks on swap, which again is what I think you
want.

Good luck.
