They're midlayer, broken, and because of the old gunk, we can't fix them. For examples see the various checks in drm_mode_object.c against dev->registered, which cannot be enforced if the driver still uses the load hook.
Unfortunately our biggest driver still uses load/unload, so this would be really great to get fixed.
