That kind of setup works fine here on stable/8:

tpx32# uname -a
FreeBSD tpx32.icir.org 8.1-STABLE FreeBSD 8.1-STABLE #3: Tue Nov  9 15:15:54 
CET 2010     
tpx32# ngctl l
There are 3 total nodes:
  Name: em0             Type: ether           ID: 00000001   Num hooks: 0
  Name: wlan0           Type: ether           ID: 00000008   Num hooks: 0
  Name: ngctl7968       Type: socket          ID: 00000009   Num hooks: 0
tpx32# ifconfig vlan0 create
tpx32# ifconfig vlan0 vlan 101 vlandev em0
tpx32# ngctl l
There are 4 total nodes:
