Usually wined3d does the window setup. I recommend to take a look at WineD3D's AcquireFocusWindow and SetDisplayMode

The problem is somewhat more complicated though - there's swapchain_setup_fullscreen_window and swapchain_restore_fullscreen_window, but wined3ddevice::Setdisplaymode doesn't call the swapchain(because there may not be one if ddraw hasn't created the primary surface yet).
