Hm...  In the original code we had the config entry but the code to
support this was actually disabled.  Now we are turning on the config
entry by default but the module parameter defaults to disabled.  I think
the documentation is a bit tricky because it should say that actually
enabling the config is not enough, it's still disabled.

Do we really need the config to be there?  Distros are going to enable
it.  Who is it who wants to disable the config?  Also is it better to
default to off or on for this code, what are the upsides and downsides
of that choice?
