IOKit drivers are just a special type of kernel extension for
implementing device drivers using IOKit. They are initialised slightly
differently, for example- typically for a kext target you'll do some
init when the kext is loaded, for an IOKit driver you won't do any
until you've matched a device and the runtime is instantiating one of
your classes.
