Following in-person discussion, we've concluded that we have to make a
mechanism to avoid the hypervisor exposing both ports to all guests;
as that would make us fail certain parts of the Windows platform
validation tests.

So we're intending to invent an HVMPARAM to control old or new ACPI
port location, which will default to old, and the new hvmloader will
set it to new.
