At this point I really don't care - mainly because of the lack of support
from the community for sorting out these problems and testing solutions
to them.

It's the simplest solution for the corner we find ourselves in with all
this crap, and avoids any possibility of any side effects caused by having
different behaviours from the same kernel.

I've merged it into my tree and I'm intending to push it upstream.  We can
then readdress it later once we have the real v6v7 crap fixed.
