It's quite possible - can we have DSDTs for the boards in question so we can
quickly check if this is a possibility? (Basically, to see if they have
PNP0C14 devices - if they don't, then I'm afraid it's nothing to do with
WMI).

It's quite possible that the BIOS accesses the device either from ACPI
AML or possibly even from SMI. In that case it would be quite reasonable
for the BIOS to reserve that region to prevent another driver from
loading and trying to take conflicting control of the device. One has to
be careful before assuming that any such reservation is bogus.
