That should be pretty straightforward using priority queueing.
Yeah, except I have those pesky DMZ hosts that I am trying to get full
speed connectivity to. Too bad the router isn't smart enough to run
IPSP, or some like tunnelling protocol, or I could get a virtual
interface for the outbound traffic.

That's because you're trying to make CBQ work like PRIQ. :)
Well, I thought that was what I wanted--to make a CBQ subqueue PRIQ
instead. I didn't actually try that, though. Should I have?

I don't understand what you're trying to achieve here; the labels
are confusing. You have "lan" and "dsl" in the same category, but in
my mind those would be two completely separate interfaces. Also you
appear to be attempting to apply queueing policy to the LAN interface,
but you really need it on the DSL interface.
"q_lan" is for my DMZ hosts that I want full speed connectivity to.
Perhaps a poor choice of names.
Your experience suggests that there should be a way to get what I
want, the only question is how...
