For ppc64 systems, it also depends on what class of arch it is presenting. I would expect a CHRP setup for ppc970, but I have no idea. If you send me an ssh pubkey, I can get you an account on a G5. That should work for anything except kernel or glibc debug. > Doesn't Fedora PPC64 have a 64 bit kernel and 32 bit userland?
