not really. the drivers for RME devices are PCI-species independent. the
PCI bus doesn't really exist for them, which is why the same driver can
interact with the (old) cardbus version as if it is directly on the bus.
drivers see address spaces and registers, not the bus.

RME devices do not load "firmware". What gets loaded is really just some
configuration data for the I/O box.
