The updated patch here partially fixes the problem, the EAP packets will
be passed now.

http://people.freebsd.org/~thompsa/if_trunk-20070409.diff

The remaining issue is that when the wireless interface is added to the
trunk it will get a down/up as part of changing the MAC address. This
causes wpa_supplicant to close and it doesnt get relaunched. Manually
starting wpa_supplicant works but I need to find a way around this.
