0 - thinking about it, there's the other possibility that the (custom)
hardware in question takes longer to enable its PCIe side which didn't
matter on the PCBIOS system it was developed on since that took long
enough to boot.

Not at hand, sorry.
Essentially, the kernel determines a 0 BAR for the device and its
bridge and starts allocating them in the region given by ACPI.
ACPI reports the extended region, but the registers we modify in this
change don't cover it completely.
