Well, this is all nice but I was wondering about _real_ examples.
When you are talking about "connecting" or "plugging" you have to keep
in mind actual bus interconnect. So far AFAIK PCI (and derivatives)
are the only cross-arch bus.
So basically, you have no _real_ life examples, so I'm wondering why
people need this "arch-independent" non-PCI I/O accessors for
something which doesn't exist.
I think the reason why Linux doesn't have this stuff follows from the
previous paragraph.
