A guy named Dirk Ehlke wrote a modification to the old OpenAL SI to do 
exactly this several years ago, including adding new functions to set 
the the speaker positions and position the physical listener within the 
space.  This is a link to his work (I checked and it's still good):

I have no idea if his version still works at all, but it seems to be 
exactly what you want to do.
