... Well, it works for me. I suspect the fix for bug 37399 doesn't work for you because the hack you're using for this one isn't quite right, e.g. because it depends on the surface getting lost to set/reset the palette, but we'll just have to wait and see after Wine 2.0.
Sounds like a plan, I'll look forward to testing when you're ready.
