You're looking for something along these lines:
cloned_interfaces="lagg0 vlan0 vlan1"
ifconfig_lagg0="laggproto failover laggport em0 laggport em1 up"
ifconfig_vlan0="vlan 2 vlandev lagg0 up"
ifconfig_vlan1="vlan 3 vlandev lagg0 up"
This will give you failover for your lagg(8) interface, I believe you
can also use something like etherchannel.
