It fails to detect in both cases.

For this particular instance, I'm now trying increasing the kbd reset
delays. It may just be recalicitrant hardware. But it may also be
something screwy in the ACPI. All the ISA devices look at an enable bit in
system I/O space and skip their _CRS functions if its cleared.

I'll start a new thread on this since its not routing-related.
