Yes, you should be able to use a 4k-native backend for a 512b-based
guest with this series (at the cost of some performance, of course).

Thanks for your testing offer!

Sure, I've included it now. For your test, it's probably easiest if you
pull the updated version from here:

    git://repo.or.cz/qemu/kevin.git align

Do you think you'll run some tests already today? If so, I could wait a
bit with sending out a v2 and see what your first results are.
