Well, dfeeling "armed, and dangerous" with the new knowledge
gained from Mateusz Guzik, Freddie Cash, and Glen Barber,
I downloaded CD1 of RELENG_9, and installed it.
I attempted to use the suggestions previously provided.
However, they were either rejected, or quietly ignored. :(

with: ifconfig_ue0="ether ##:##:##:##:##:##; DHCP"
the ether isn't honored (ignored)

ifconfig_ue0="ether blah blah blah"
ifconfig_ue0_alias0="DHCP"
throws an error (but spins by too fast to catch)
/var/log/messages would probably reveal it.

ifconfig_ue0="DHCP"
create_args_ue0="ether ##:##:##:##:##:##"
create_args is simply ignored.

I don't get it. I've tried every imaginable incarnation I
could possibly conceive. Is it even possible? I had really
hoped to turn this into a gateway, and while Linux will
"clone" the MAC(3). I don't trust it (security wise).
Is Linux' DHCP more robust than BSD'?! Hard to imagine,
but I'm completely at a loss.
