I'm not too convinced this is such a difficult problem to figure out.
We already have most of logic in place and the only thing missing is
how to switch it.  Wouldn't something like the following work?

* Add a sysctl knob to enable asynchronous device probing on module
  load and enable asynchronous probing globally if the knob is set.

Alternatively, add a module-generic param "async_probe" or whatever
and use that to switch the behavior should work too.  I don't know
which way is better but either should work fine.

I take it by this you meant a generic system-wide sysctl or kernel cmd
line option to enable this for al drivers?
