+ * 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.
+ *
+ * XXX use an intermediate #define for the tag/handle
