if I do:

LD_PRELOAD=./mylib.so wine /games/World.of.Warcraft/WoW.exe

it also prints that 'can't preload' message, but if I supply the full 
path to the library, it doesn't print that anymore. But since I've 
supplied the full path to LD_PRELOAD, I have no clue what might cause 
this error.

After I've changed some parts of libaoss.so it started to work, I had to 
comment out one function call, replace a return value in another place 
and add two function calls to the snd_pcm_read/write functions.

What I've done is described here: 
http://gentoo-wiki.com/HOWTO_ALSA_and_TeamSpeak_on_amd64

read the section 'compile patched alsa-oss' to find out what exactly 
I've changed.
