But that is _fine_.
You don't ant to auto-unload the yenta module anyway as far as I can tell:
that would be bad when the laptop suddenly without any user action stops
caring about card insert/eject events.
So you _want_ to have the module locked down, until the user explicitly
decides to get rid of it, at which point the user (maybe an automated
shutdown script) can explicitly kill the cardbus watcher deamons and
unload the module.
