I can confirm this problem with latest catalyst/ATI driver to date (10.6) and wine version 1.1.44. Please if you know why this happens or a possible solution I will very much appreciate it. I'm looking forward for a response. Thanks.
Ok, I found the solution to the problem with GLX error. It was quite simple, just had to install the catalyst-utils package for 32 bits, the name in ArchLinux is lib32-catalyst-utils, and that solved the problem. The game is running just fine now. Thanks.
