It was 32bit version of Warsow. By the way, you can try TrackMania for yourself, it's freeware game.
I was able to try both games yesterday. I noticed some anomalies with Warsow, in that it didn't sound like it used the rolloff properly, but it used all the speakers correctly as far as I can tell. TrackMania also used all the speakers correctly.
Note that Warsow by default wants libopenal.so.0, not libopenal.so.1. Some distros may still have the older lib in a different package that can be pulled in by pre-compiled dependencies (eg. libopenal0), although the correct way to handle it would be to make a symlink from libopenal.so.0 to libopenal.so.1 (I haven't yet run across an app that has an issue with this).
Out of curiosity, are you able to use mplayer's ALSA output with a 5.1 channel sound and 5.1 (6) channel output?
