Client crashes on ubuntu 7.04.

[azagor1]

I have red all the posts connected with this subject and some of them were helpfull but my problem is not completely fixed yet. I have used driconf to enable S3TC. I can turn on the client. Sometimes I can even see this ATI/AMD screen. Unfortunately soon after that client crashes and I can't enter the game. My graphic card is Radeon 9250 and I am using open ati drivers (glx). Below I am giving you my crash backtrace:
