I think instead we should go the other way
and simply delete the code
for _GTS and _BFS support.
The evidence is that while it is documented in the ACPI spec,
no OS implements it -- for when we tried it, we found some
systems that shipped AML that doesn't work.

ps. yes, we should also petition the ACPI authors
to remove _GTS and _BFS from an upcoming revision.
