It isn't of interest to most people, but I got an initial run working so I'll post about it
As posted in my Linux data sharing with Windows thread I've now got Dawn of War v1.5 running under Fedora Core Linux. Everything seems to run fine on an initial attempt, and I may be able to get better graphics if I actually work on it and change some settings rather than just going "does it work....yes, it works! announce it to the world!"
A Screenie of my first attempt is available (220KB) and instructions may follow.
