I would like to see a change in the config machinery so that *_attach()
can fail, which would then stop the device from being accessible.
As it is each driver (where attach can fail) needs to have a flag indicating
if it is really working.  Ideally, an attach should never fail, but unfortunately
that's now how the world works.  A device can stop working at any time,
even during attach.

My proposed change is rather large.  Each device driver needs to be modified,
but in a very simple way.  Just change the return type to `int' and add a `return 0'.
