What I think thorpej means here is (of course, this being thorpej)
true.  But I suspect that widupwm and/or brook are talking about
something else.

There are at least three things here that can reasonably be called the
device tree.

(1) The tree passed from the booter to the kernel.

(2) The tree (or more properly directed graph) of attachments described
by the kernel config.

(3) The tree actually found by autoconf.

I suspect thorpej is talking about (1) but brook and/or widupwm are
talking about (2) or (3).
