Project1999 works fine under a stock Wine install; I'm using wine-1.4.1 from the Ubuntu 13.10 repositories, plus the patched d3dx9_30.dll and custom eqclient.ini mentioned earlier in this thread.
I think the pieces needed to get this working are somewhat scattered around, so I wrote this thread to show how I've done it:

Hope that helps!
