Ugh I don't think we have done a very good job at providing fallbacks (several compatibles) for this hardware. Just looking at the list makes me suspicious. The fallback scheme is pretty hard to maintain when vendors are a bit unclear on whether things are really compatible or not, and sometimes they are compatible but rather not say :( Yours, Linus Walleij
