This was made with WINE in mind, but works for codeweavers (at least as-of what was current during the "Lame Dusk" give-a-way)

That page links to a psinstall.zip with an exe inside. Use that as the installer executable.
Create your own "bottle" for Planetside. I actually had a full windows install and dropped it's data over into the folder created by the Station application after interrupting the download process. After the drag & drop, all my windows preferences came over and the resolution was set perfectly.
The only problem have be game crashes, but since that's a normal part of Planetside it is difficult to isolate if it is the fault of codeweavers or Planetside
