I'm currently working on xl(4) conversion, and will take care of fxp(4)
once it's done.  I'd be happy to send you patches so that you can test
it on alpha and fix busdma so that it works if necessary.  I would
definitely feel bad about breaking alpha support since those drivers (at
least xl(4)) currently work on alpha with the alpha_XXX_dmamap() hack.
