Sounds like you're not getting the module loaded. By your description
above, you're no longer sending tagged frames over the trunk.

My rc.conf bits:

ifconfig_em1="up media auto"
cloned_interfaces="vlan100"
ifconfig_vlan100="inet xx.xx.xx.254 netmask 0xffffff00 vlan 100 vlandev em1"

# tcpdump -c4 -nvvvei em1

Seems to work fine (it's the -e switch that does it).

Hope that helps.
