Why don't you use gbde. It is in your distro at /sbin/gbde
Make a file with dd and format is with gbde and newfs:

dd if=/dev/random of=file bs=1k count=1000
gbde init /dev/md0
mdconfig -a -t vnode -f file
gbde init /dev/md0
gbde attach /dev/md0
newfs /dev/md0.bde
mount /dev/md0.bde /mnt

#and you are ready to use the filesystem at /mnt
#watch out for the sequence of umounting:

umount /dev/md0.bde
gbde detach /dev/md0

#for mounting you do:

gbde attach /dev/md0
mount /dev/md0.bde /mnt
