The chip sets often contain parts that are connected to the PCI bus, 
and others that are not and can't decode PCI configuration cycles
(e.g. buffer or driver chips).

I didn't have time to check this on Intel's web site, for these
particular devices, though.

Well, it just seems to fit on one line in the boot message log.
If Intel wants the chip to be known by that name ...

Thanks! Looks fine ...

This is one of the least dangerous patches I can imagine, and I
think it should be allowed in ...

Sorry, I'm overloaded at my job, currently, and did not have time
to commit it before the code freeze.
