Hi guys,

I finally got time to look at this issue. I think this series should fix
the problems that have been seen. I've tested this fairly thoroughly
with a qemu script, and also a few boots on a real machine.

If you can test it with your setups that would be great. Hopefully there
isn't some obscure case I've missed.
