Actually there is a way.  I too have not been satisfied with the tmpmfs 
features in rc, so for some time now I've simply created a hard link:

	cd /sbin && ln -f mdmfs mount_md

and then used an entry like this in /etc/fstab:

	md		/tmp		md	rw,async,-Sp1777,-s768M	0	0

This works great for me.  A simple patch to mtree could make this hard link 
part of the base system.  Nothing else is needed.
