No, Plan 9 on the x86 runs in 32-bit protected mode, not real mode. If you're not willing to use AMD64's compatibility mode at all, you essentially have to do a full port: new compiler, assembler, loader, libmach, and some kernel work. Widening pointers to 64 bits will take scrutiny of and changes to the kernel.
