Hi David,

I've spent a bit more time on this, and even with the patch I'm still
seeing migration issues which need further investigation so I'll have to
pick this up again after the upcoming release. On the plus side I've
been able to spend some time this week updating Cormac's OS9 GSoC
patches for upstream, so I'd be grateful if you could take a look at
those in the meantime.
