Yes (or it could be loaded based on module dependencies when hotplug
loads the first low-level driver).

No need -- you can load the ULP before any devices are present (its
add() method will get called when low-level drivers create devices).
Or one could add /etc/hotplug/infiniband.agent or something like that
to do any initialization required.
