The way struct wined3d_bo_address works is that if the "buffer_object" field is non-zero, the "addr" field is relative to the start of the corresponding buffer object, and otherwise it's relative to the start of system memory. I.e., the correct check here should be for src_bo_address.buffer_object and dst_bo_address.buffer_object being non-zero, and you should be able to use src_bo_address.addr and dst_bo_address.addr instead of src_buffer_mem and dst_buffer_mem in most other places.
I'm not sure I can do this. If a buffer is double-buffered, I still have to copy through system memory, even though the "buffer_object" field is non-zero.
