What I have found so far is that the native dxdiagn.dll retrieves the device capabilities using IDirect3D9Impl_GetDeviceCaps. However, I was unable to find any values for the caps struct, where the native dll would determine that b3DAccelerationExists was supposed to be false.
You are not allowed to look at what calls the native dll makes, that's an implementation detail. The only thing you can do with native is to write test cases to determine the externally visible behavior.
