The blackbird maintainer knows about it already. But I'd forgotten about 
the case where you can have both a blackbird and a ivtv card in one 
box. I've modified the ivtv firmware load code to also accept a 256 KB 
firmware (just run 'head -c 262144 v4l-cx2341x-enc.fw >new.fw' and copy 
new.fw over v4l-cx2341x-enc.fw).

Thanks,
