Sorry to reply to myself here, I forgot to add: The problem is still
present in 6.0-RELEASE, and can be seen while running sysinstall.
Haven't tried 6.0-STABLE (can't get -RELEASE to install due to
unrelated bug bin/88872). According to cvsweb, 6.0-RELEASE has the
latest Intel driver.

Also: The bug you're seeing may be unrelated to the bug I was seeing,
but I suspect they may be similar. Arps just don't seem to be going
out like they should
