Can you add an example of the failure symptoms?
I can.
Should I be waiting for a v3?

Shouldn't you update load_elf() and co now to take target_ulong
arguments? This would fix this error generically for all archs.
That is an option, but as load_elf() is called by every other machine
I don't want to break them. It's entirely possible that other machines
rely on this behaviour and changing it will break them.
