Note that those probes happen for specific buses rather than for specific 
drivers.  The routine that does this currently is static 
(devclass_driver_added() in sys/kern/subr_bus.c).  What specific problem are 
you trying to solve?  You might be able to use BUS_DRIVER_ADDED() or 
device_probe_and_attach() to achieve what you are trying to do.
