I don't think you worry. We assume that the BIOS configured them correctly
as otherwise the machine wouldn't boot. As we don't change this
configuration, no big deal. These chips are the ones between the PCI bus
and the CPU, and between the PCI bus and the ISA bus.

Yes (assuming your X server supports it). All this message means is that
the kernel doesn't have a driver specifically for it.

No one has added support for these PnP tags.

Take care,
