Can you look at the v2 patch? It seems to work on every configuration I
throw at it. Keep in mind that setup_data is only used very, very early.
I can think of a few other places to put it too, looking at the x86
memory map, that will survive long enough.

I think this might actually be a straightforwardly solvable problem if
you think about it more basically.
