I spoke to blueness in #gentoo-powerpc and he basically said the same thing, that the existing ppc64 keyword should suffice. He noted that we do not have different keywords for every mips variant because that would be a lot of keywords! Stage 3 tarballs (possibly cross-compiled) could be provided and some initial work could be done to ensure they actually function but beyond that, endian issues would simply be dealt with as they are reported. -- James Le Cuirot (chewi) Gentoo Linux Developer
