* ACPICA's rather gung-ho approach to hardware resource ownership is a little
* troublesome insofar as there is no easy way for us to know in advance
* exactly which I/O resources it's going to want to use.
*
* In order to deal with this, we ignore resource ownership entirely, and simply
* use the native I/O space accessor functionality. This is Evil, but it works.
