16-bit support and hardware virtualisation extensions are 2 totally
separate and orthogonal issues.

Secondly, desktop hypervisors such as VirtualBox and VMware can do
software trapping of Ring 0 instructions on systems lacking hardware
virtualisation extensions, so they will still work and the method I
suggest will still function. I'd expect that performance would drop
15% or so, though.

I suspect that 16-bit code compatibility will remain in x86-64 until
the end of its days, but I could be wrong...
