Interesting on the fw/microcode as what I read indicated this can't be
fixed in fw/mc. Though perhaps fw/mc changes could help in some way,
in tandem with the OS.

Again, from what I read, this won't be a fw thing, so I don't think
we'll see the above scenario. If we do -- if fix=fw+os -- then we're
in for a world of hurt because most mfr's stop updating fw after their
cycle, usually max of 3 years, some much less. That would leave a
whole slew of mobos unfixable. Good way for the industry to force a
rapid upgrade cycle!!! That might really get Intel in trouble,
though... $$$ lawsuits.
Of course, it's early days, so I could be way offbase, and even if I'm
correct now, my info may be wrong in a few days/weeks.
