A weird thing about that.. I compiled it in, "device vlan" ..but the 
modules is loaded. And when I boot, I see it trying to load the kernel 
module again after its loaded. If you can suggest why the module is 
loading, I'll fix it, and restart my bpf process to see if I can reproduce.

I have nothing telling it to do this.. except in rc.conf I have:

cloned_interfaces="vlan2"
ifconfig_xl0="DHCP"
ifconfig_fxp0="10.1.0.5 netmask 255.255.255.0"
ifconfig_vlan2="inet 192.168.0.10 netmask 255.255.255.192 vlan 2 vlandev 
fxp0"

dmesg shows:
ipfw2 initialized, divert enabled, rule-based forwarding enabled, 
default to accept, logging disabled
