Warner Losh fa949fc86d if_ral_pccard does not depend on pccard module directly, but rather
depends, like all other pccard drivers, indirectly through kobj on
pccard.  Therefore, it is not appropriate to force pccard to be loaded
when if_ral.ko is loaded.  This makes it possible to load if_ral w/o
loading pccard.ko on, eg, pci only systems.
