I have both with 'y', but I think it should be fine the way you have it too. If I read the sources/makefiles correctly, all you need to do to get the missing symbol is a 'modprobe firmware_class' (I guess if that works, I should add a request_module() or something in there to make it load that automatically). Note that the blackbird part of the driver still is not 100% ready (you now still need to scale& unmute the audio correctly manually for the mpeg stream to contain usable audio&video). It's on my todo list, when I get some time (sorry 'bout the slowness).
