The situation which I wanted was to have a port with three or four tagged
interfaces visible to the kernel. Of those tagged LANs, I then wanted to
have some of the visible on another physical port, untagged.
The tagged port goes into a (cisco) SOHO switch, and talks to a bunch of VMs,
etc. The untagged ports get wired to a couple of other "critical" systems:
the other AP in the house, a VoIP phone (via PoE injector). This lets me
put the 3800, and phone on a UPS seperate from the switch and VM hosts.

So, what I want to do ought to be possible, I've just failed to get it
