Change -d11.0 for -d11.1 ;-)
It's there -> http://download.opensuse.org/distribution/11.1/repo/oss/suse/x86_64/openal-soft-1.5.304-1.33.x86_64.rpm
When running the game I get:
OpanAL: error creating context: AL_INVALID_OPERATION
OpenALSoundSystem ERROR: cannot create SoundSystem.
funguloids: openalsoundsystem.cpp:510: void
OpenALSoundSystem::update(): Assertion `mStreamPlayer' failed.
Abortado

It's supposed to be the same API, I suppose the patch is needed
because the code was using an undefined behavior or something...

Ok.

Ok.

The binary links against libmad. From
http://funguloids.sourceforge.net/readme.html#howtoplay it seems the
game only comes with Vorbis audio, but if linked against libmad an
user could also add MP3 music in $HOME/.funguloids/music/.

The openal-soft package also provides openal, so you can't force one.
Also, since both packages can't be installed at the same time and
openal-soft seems to be better it would make more sense to force
openal-soft instead (but perhaps openSUSE plans to just remove openal
and rename openal-soft to openal in future versions).
Anyway a "ldd -u -r" says libopenal.so.0 isn't a real direct depency
(I don't know about openal, but I suppose funguloids is using openal
only through alut?). If it's removed you would not need to select one.

An alternative is to add a provides to the OBS package instead...
