Hello Forum,
i want to give all tux fighters this information:
The X-Fi series of products are not supported under Linux. Closed-source drivers will be available for the X-Fi series of sound cards in the second quarter of 2007. These drivers will have full support for ALSA (playback, recording, mixer, MIDI, synthesis) and OpenAL 1.1 (with EAX effects).

So we can hope that we can play Quake Wars with EAX, if a linux client will released.
