I think only gentoo has real 64bit (all packages built as 64bit), but you don't really want to run gentoo. Most other powerpc linux (debian, YDL, suze, mandrake seems to have dropped ppc lately i think) are either pure 32bit only, or use a 64bit kernel with a mixed 32/64 bit userland. Friendly, Sven Luther
