Have you tried to just drop the native d3dx9_30.dll directly in the game directory and keeping Wine's d3dx9_30.dll and d3dx9_36.dll in windows/system32?
That is exactly what i did. Left the DLL untouched in windows/system32 and put the 30 & 36 to the same dir like Flatout's exe. Then you don't even need to mess with winecfg and native settings.

But the reported bug, the graphical bug in fact, is fixed, well for me at least.
It is not fixed, but work arounded. Without d3dx9_30.dll there are still red shadows. Like i alredy wrote at comment #11.
