And I don't even know where you are going with positional cue audio...what the hell is that? There's nothing in EAX's technology description that involves positional cues, they are all environmental profiles.
Those profiles are for external use, to apply to your normal desktop or overtop of the in-game experience. "real world" means actually changing the sounds in a game based on where you were in a level to more accurately reflect your environment. it doesn't describe "positional cues" but EAX is able to make the direction a sound is coming from more apparent when you're using 2 channel speakers/headphones.
For example, the original halo was able to use EAX. say you were inside one of the bases on the island map and a tank fired outside, EAX made the sound reverb like it would if you were in a tunnel, but it sounded normal if you moved outside. Without EAX it sounded the same whether you were inside or outside.
One of the main reasons MS dropped DirectSound in windows vista was because of the OpenAL audio emulation standard and the higher adoption of surround-sound equipment which made EAX obsolete.
If you still want to get EAX effects from games like halo you can use creative's ALchemy program. ALchemy takes the Directsound/EAX cues and wraps them into the OpenAL stream.
