Perhaps I copied it down wrong. I did this in a 2.6.16 UML instance...

sh-3.00# mount -t tmpfs /tmp /tmp
sh-3.00# cd /tmp
sh-3.00# mkdir woot
sh-3.00# mount --bind woot /var
sh-3.00# cd /var
sh-3.00# mkdir sub
sh-3.00# mount --move /tmp sub
sh-3.00# ls -lR
.:
total 0
drwxrwxrwt 3 root root 60 May 15 15:57 sub

./sub:
total 0
drwxr-xr-x 3 root root 60 May 15 15:57 woot
ls: not listing already-listed directory: ./sub/woot
sh-3.00# find .
.
./sub
find: Filesystem loop detected; `./sub/woot' has the same device number and
inode as a directory which is 2 levels higher in the filesystem hierarchy.
./sub/woot
sh-3.00#

Works for me. :)
