I suggest you just start again if you are getting binkw32.dll errors.Remove your wine prefix (rm -rf ~/.wine) and re-install.After you've installed oblivion, run "wine Oblivion.exe" from the installed oblivion directory, under a terminal.Check the terminal output and you'll see errors with d3dx9_*.dll.Get hold of this DLL either through another windows installation or just google it.Don't bother installing the full directx installation as it can cause additional problems. Oh and the appdb page http://appdb.winehq.org/objectManager.php?sClass=version&iId=7506 suggests another way of getting hold of the required DLL.
