Ok, first thing I'd do is do a clean install using 9.10 and start over. There were a LOT of improvements in 9.10 over 9.04 that solved SU compatibility issues... Including video driver updates, etc. Don't do an "upgrade" as it tends to leave some of the old libs and files around, messing things up. Ask me how I know... Your WINE is the latest I'm aware of. It "should" load the ia32 libs for you by default, but you can always check using Synaptic. You HAVE to have the ia32 libs because even though you're using WINE, it relies on some 32-bit libs to interact with the LINUX environment. About the only thing I've loaded as "extras" in WINE using winetricks were a few fonts and a couple of MS runtime libs. FWIW, I run Xubuntu 9.10 64-bit with an Intel driver, SU 7.1, Twilight Renderer and SketchyPhysics all under WINE 1.1.39 without any issues at all so I know you should be able to as well... Cheers.
