I'm sorry but I don't get your point. Qemu should work on all cpu. 4Kc &
friends are currently supports (according to the -M switch) and iirc
theses beasts have 32bit address path not 64. I really fear that setting
64 will break them. That's why I've sent this patch. If keeping 64bit
breaks 4Kc and if switching to 32 break r4k, an other solution will have
to be found imho
