Intel has proposed X86-S which jettisons most of the 32-bit and
16-bit parts of the architecture. That might let them clean up their
microarchitecture (or at least provide a larger microcode patch
area 8-).

I expect there will be unpleasant surprises if S-mode processors
make it to operating system developers (outside of "most favored
nation" ones like Microsoft).
