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.
