I checked with dumpfs that memstick.img is UFS1.

Also, mounting /dev/md0 confuses the kernel into ultimately panic'ing,
since /dev/md0a is the proper slice. For the mfsroot.gz file from the
CD ISOs:

# mdconfig -a -f mfsroot
md0
# mount /dev/md0a /mnt
# ls /mnt
ls: /mnt: Bad file descriptor
# cd /mnt
cd: /mnt: Not a directory
# vim /mnt

panic: ffs_read: type 0

kdb_enter()
panic()
ffs_read()
vn_read
dofileread()
kern_readv()
read()
syscallenter()
syscall()
Xfast_syscall()
