2.1 doesn't have this limitation.

I spent a minute checking this in -current :-).  Result:

Device      1024-blocks     Used    Avail Capacity  Type
/dev/wd0b         33280     1512    31704     5%    Interleaved
/dev/vn0h          2048     1472      512    74%    Interleaved
Total             35200     2984    32216     8%

This is for a fully labeled vn0 (vn0h is a bogus alias for vn0b if
labels aren't enabled).
