Unfortunately, Harald's patch (well, maybe it was updated in the meantime) lacks byteswapping fort the multicast address filter and the encryption keys, meaning that they won't work. You can fix that by adding the correct SwapBytesBlock calls like for other calls (you can compare to my Airport driver to see how I did it, note however that my current airport driver lacks fix for multicast addresses, I'll post an update soon but I'm chasing another problem right now).
