found it!
you need to start VPS and then do bind mount, since vzctl redo mounts on
VPS start, so my 1st proposal for you was wrong. sorry :)
the best way you can do it actually is to insert your special mounts in
VPS mount script which will be automatically run on VPS start.
Please note, on 2.6.8 kernel bind mount is still rw :(
