Ouch: as described above, I tried

net.ipv6.conf.eth0.accept_dad = 0

which didn't work ... but I'm using wlan0, so I tried

net.ipv6.conf.wlan0.accept_dad = 0

and that works. So turning off DAD / Duplicate Address Detection is a much better workaround:
1) I do get a private extension IPv6 address (on top of the MAC based IPv6 address)
2) no more annoying messages in dmesg

NB: It's still a bug.
