The installation had some minor bugs, as not showing the game name in the installer.
The game name isn't shown in the crossover applications under config.
Patching didn't work at all, not even with the newest patch script.
I had to patch it up on Windows and copy those files to my ubuntu distro.
Will try to patch up with the script when a new patch comes out.
So best sollution is that you have BF on a USB stick or on annother PC with windows installed (your's or of your friend etc), and patch up there.
After just copy the files to your linux distro.
Game runs without problems in windowed mode, but keyboard isn't working at all.
