Oh right now I remember. The same problem exists: EFER is not saved in the 32-bit state save map. AFAIK all processors with XD also have long mode. That said, qemu-system-x86_64 and no -cpu option should work even with Ia32 PEI/DXE/SMM and no -cpu option. In that case you could use XD. Now if only Intel made the *full* format of the state save map public, we could emulate everything more accurately... I'm told it's in the BIOS writers guide.
