It's OK--I have a couple extras. If it was really important I would have
stopped when the instructions failed to install it as a second stage. I've been
doing embedded Linux for so long I can't remember if this is a first or second
brick. :-)

Cool. One of us should update the wiki.

http://downloads.openwrt.org/attitude_adjustment/12.09-rc1/kirkwood/generic/
shows both, although I can't figure out why on casual examination. They aren't
built when I do a board-specific build at least. Are there stale files on the
buildbots?

Luckily I have a J-Link in a box somewhere, and a Bus Pirate. What I need is to
build a connector, and I haven't gotten to that yet. Uh, plus figure out which
version of OpenOCD is the stable, working version for the platform--that's been
a problem before.
