I'm also looking into it for s390 right now. So, in one of your replies you mentioned that you "have proposed (but haven't finished this due to other stuff) a solution for this". Have you covered any part of that solution yet? Could you please point me to any relevant discussions on this matter? Thanks, Mikhail Zaslonko
