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.
