em(4) VLAN + PROMISC still doesn't work with latest CVS version

I recently upgraded to 5.3 on a system, and manually upgraded
src/sys/dev/em/* to the latest RELENG_5 versions. (22.214.171.124 of if_em.c)
While the VLAN side of things works better than the stock 5.3 version,
there still is this problem:
ifconfig vlan1 create
ifconfig vlan1 vlan 1 vlandev em1 link0
ifconfig vlan2 create
ifconfig vlan2 vlan 2 vlandev em1 link0
ifconfig vlan3 create
ifconfig vlan3 vlan 3 vlandev em1 link0
ifconfig vlan1 inet 192.aaa.bbb.129 netmask 255.255.255.0
ifconfig vlan2 inet 64.ccc.ddd.61 netmask 255.255.255.192
ifconfig vlan3 inet 64.eee.fff.61 netmask 255.255.255.192
ifconfig em1 up
ifconfig em1 promisc
If I do this, vlan1 and vlan3 work fine. Vlan2 can receive packets, but
anything sent out vlan2 doesn't seem to be heard by any foreign hosts.
Setting "ifconfig em1 -promisc" makes all vlans work properly.
This is better than the stock 5.3 version of em(4) where none of the
vlans worked, but something still isn't right.
Is this a known problem still or am I just doing something wrong?
