Sure - but what determines the port - or rather, where can it be
probed?
Data from Samuel suggests that the ports are configured by the BIOS,
because the PNP0c02 device owns them ("system peripheral: other")
according to ACPI tables.
Do you know if the base port is readable from a fixed register such
as one in PCI config space?
