Does almost everything get loaded and auto-unloaded at boot time?
If so that that isn't really a good idea.

It also sounds like manual unloads of drivers can happen when the
device is open - and that is also bad.
A manual unload probably isn't going to race with open or close though.

Disallowing unload completely would be a pain when developing drivers.
