If you do
ifconfig em0

what options does it show ?

# ifconfig em0
em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
         options=1b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING>
         inet 10.1.1.2 netmask 0xfffffffc broadcast 10.1.1.3
         ether 00:01:80:54:b8:df
         media: Ethernet autoselect (1000baseTX <full-duplex>)
         status: active
#

Is vlan_mtu there ?  Also, when you create the vlan interface, what options 
do you use to create it ?

I am using 5.3-STABLE FreeBSD 5.3-STABLE #1: Tue Nov  9 13:11:18 EST 
2004  and it works with large frames.
