You are correct. System p is much different. POWER has a bit in the page table entry which says "this page (bunch of pages) is little-endian. Make sure register LOADs and STOREs work appropriately in this address range". Lx86 depends on this architectural feature, which z does not have.

A philosophy is not the same as a commitment, If you really have to have it, then http://bochs.sourceforge.net/ It has been proven to work (very slowly) in the past.
