It is my understanding that EAX (Environmental Audio Extensions) and surround support for DirectSound are two independent things. EAX is just a bunch of environmental audio presets, and has nothing to do with hearing enemies coming from behind you in 3d games.
I can select 5.1 audio output in Team Fortress 2, but there is no audio from the rear speakers and when I restart the game the sound option is reset to stereo.
