Even for 32-on-64 we need to control the guest's address space properly (so we don't do things like gratuitously failing mmap); in theory you could do that if you could guarantee to mmap 4GB contiguous at startup to parcel out to the guest, but it would be simpler and more consistent to just use softmmu in all cases. -- PMM
