Hello David.

I tried out this as well. I did not observe that it should be the MAC 
address of the wired interface at first, so I put the wifi MAC in 
rc.conf and got a page fault 12 when I tried to boot with the lagg 
configuration. I've now changed the MAC but I stil get the page fault :-(

I'm not sure what you want to achieve with the background_dhclient.
I use
ifconfig_lagg0="laggproto failover laggport em0 laggport wlan0 SYNCDHCP

SYNCDHCP waits for the dhcp offer so no network services are started 
before the  NIC gets an address.
