Been playing with the latest openSUSE release, 11.1, and as I’m on holidays thought I’d try and get CIV4 working.
It appears to work fine, except for sound which errors complaining about an alsa pcm-pulse library issue. This is installed on the openSUSE system, but Wine needs the 32bit library. Installing this solved the problem:
sudo zypper in alsa-plugins-pulse-32bit
