I agree. A related issue is what to do if the user wants to
pass-through a device that is already claimed by another
driver. Following your comment to its logical conclusion, we should
error out, not remove the original driver somehow---imagine the mayhem
if the user loaded a module and it happily went along and removed some
other module that happened to drive the same device.
Cheers,
