Do you have "options MFS" in your kernel config?  I would also
advise you to add a "-s" option to the mount flags, so that you
limit the amount of swap space taken for /tmp.  Bad Things will
happen if you run out of swap space...  My entry (on i386 version
1.0) looks like this:

/dev/wd0b /tmp mfs rw,-s=3D32768 0 0
