There's one more thing you can try. Can you modify
IWineD3DDeviceImpl_CreateIndexBuffer in dlls/wined3d/device.c this way:

right before the "return WINED3D_OK;" (aroud line 582), insert "object->flags
|= WINED3D_BUFFER_DOUBLEBUFFER;" This will essentially disable the new memory
saving feature with the least code modification and give some hint where things
are going wrong.

I have the horrible suspicion that the game tries to access the buffer memory
after calling Unlock(). This is invalid, but happened to work with the old
code, but depends on the OpenGL driver's mercy in the new code. If this is the
case, we'll have to revert the memsave patch :-(
