Well that the PNP subsytem needs to be aware on non-std bars which claim this
IO. Imagine if PCI IO allocator in linux will for some non-assigned resource
assign same region as above. Well this wont happen because PCI io usually starts
at 1000 but in general it might be above 1000 too. I think this was the reason
for this quirk. - The ACPI pnp might claim this region too and in fact ACPI
should do that. Even more specially this quirk is here mostly when ACPI fails to
do so and the IO is above 1000 ;)
You may ignore this as "mostly harmless". No really it is harmless for you.
