OK, I've confirmed that I still get the above with both dadwifi and
bcm43xx-mac80211
A tcpdump indicates that my laptop sees its own neighbour-announce come
back, and assumes that's a different machine sending it, failing the
duplicate address detection.
A tcdump against the ethernet device (or bcm43xx from 2.6.20) does not
see the neighbour-announce come back, and so passes the duplicate
address detection, and gets an autoconfig IPv6 address.
I thought it might be the lack of IFF_BROADCAST which was fixed a while
ago, but it's still there.
kernel 2.6.20 from debian, patched with get_order() fix from 2.6.20.2
modular mac80211 stack from intel's 4.0.4 tarball, patched into kernel
bcm43xx-mac80211 from wireless-dev
dadwifi from madwifi.org subversion repository

Of course Pacman didn't influence us as kids. If it did,
we'd be running around in darkened rooms, popping pills and
listening to repetitive music.
