I think this was fixed in -current in rev. 1.93 so that the vlan 
reports the speed of the underlying interface. You might try to use that 
fix.

Alternativly you can patch bsnmp to set the speed to some arbitrary high 
value if it is 0. This would be in snmp_mibII/mibII.c mib_fetch_ifmib().
Add something like:

	if (ifp->mib.ifmd_data.ifi_baudrate == 0)
		ifp->mib.ifmd_data.ifi_baudrate = 1000000000;

just after the HIGHSPEED and VERYHIGHSPEED flags have been cleared.
