Here is a page that mentions the default positioning for some surround sound 
setups:
http://en.wikipedia.org/wiki/Surround_sound

Though the idea here wouldn't be putting the source right on the wanted 
speaker, so much as it is putting the source on a "virtual" speaker and openal 
will pan to make it sound like it's coming from there, whether there's a 
speaker or not. Eg. if you want the sound to come from the back-left, put the 
source at {-0.707, 0, 0.707} for -135deg, or for front-right at {0.707, 0, 
-0.707} for +45deg.
