I'd hope not, but it depends on what Windows does on resume. If it
doesn't do the SMM call and just does the register write instead, then
it may be that some machines are on that list because the SMM call
breaks them rather than because they need the register to be set by
hand. I'm planning on instrumenting it to check, but haven't had time to
do so yet.
