Thanks for the information.
Could you point me an example code how to declare dependency?

In my environment module1 is firewire bus drivier, module2 is sbp
driver.

module1:
DRIVER_MODULE(firewire,fwohci,firewire_driver,firewire_devclass,0,0);
module2:
DRIVER_MODULE(sbp, firewire, sbp_driver, sbp_devclass, 0, 0);
