freebsd stable - Nov 2010 - netgraph and interface nodes

Hi.

I'm using 8.1-STABLE on one of my production servers. I wrote about krb5 
problem some time ago.
Second trouble is netgraph-related.

I'm using dot1q on an em(4) card.
It's loaded as a module atm (however earlier it was in kernel).

I have ng_ether/ng_iface in kernel, if_vlan loaded as a module, but I 
cannot see vlan interface nodes in ngctl.

Is this known problem related to a driver loaded a s a module ?
Or maby it can be helped some other way ?

Thanks.
Eugene.

That kind of setup works fine here on stable/8:

I see no ng_ether module in your list, or did I somehow misinterpreted your 
query?
