in /etc/rc.conf, add:

autobridge_interfaces="bridge0"   <-- whatever you called your bridge
autobridge_bridge0="tap0 tap1 [tapn..]"
cloned_interfaces="bridge0"

forgot to add this:

Create a qemu-ifup script like this:

#!/usr/local/bin/bash
# qemu-ifup
/sbin/ifconfig $1 up
TEST=`ifconfig -a | grep member | grep $1`
if [ "$TEST" == "" ]; then
   /sbin/ifconfig bridge0 addm $1
fi
