... they should update their packages ;)

was easier that I've expected:

./configure --prefix=~/root LDFLAGS="-L/emul/linux/x86/usr/lib -m32" 
CFLAGS="-L/emul/linux/x86/usr/lib -m32"

and the package compiled without errors, copied the library to the lib32 
path and now I can play WoW and listen to music !

but the aoss wrapper library (version 1.0.10) still fails:

$ ALSA_OSS_DEBUG=1 LD_PRELOAD=/emul/linux/x86/usr/lib/libaoss.so.0.0.0 
TeamSpeak
ERROR: ld.so: object '/emul/linux/x86/usr/lib/libaoss.so.0.0.0' from

Maybe a bug in TeamSpeak itself, not initializing the device properly, 
but it works fine under native oss. I even tracked down the file and 
line on which it fails (posted to the alsa-user mailing list). So if 
someone has a clue how to fix this I'd be more than happy to test it.

Just commenting out the function call didn't help, so that call seems to 
be important for the device initialization. Seems like the function 
arguments ate calculated wrong, but I'm not a sound expert and I don't 
know what the valid fucntiion arguments are.
