I think the problem was a missing poke (qdisc_restart) in the netem timer routine, it probably worked earlier for me on other hardware because I was using different hardware that was waking up and checking tx in response to received packets.
Yes, that seems likely. Since netem doesn't account for the delayed packetsin sch->q.qlen it will only be woken up while non-delayed packets are queued.
