The default action for driver auto loaders in this case is usually to load
all of them unless specially overriden. That is because there are several
cases where one PCI-ID implements multiple functions served by different
drivers. So far there is no really clean solution to this problem and for
e1000 with PCI-E IDs it would do the wrong thing.
