I think the _PRS returned one type and _CRS is returning another (or some 
such).  I'm not sure what the "right" thing to do is in that case.  
Presumably this is while building the buffer for _SRS?  Hmm, I guess you 
could just make it able to read the IRQ out of the _PRS no matter what format 
it is.  But we might should be copying the resource that is in _PRS instead 
and building a new resource list instead of overwriting the fields in _CRS.  
That is a bit more involved.
