rescue CD isos

[Jesse Keating]

Rescue CD isos should be named by arch now, and there is i386, x86_64,
and ppc (ppc handles ppc, ppc64, mac, and chrp).

Would uses of these arches please try booting the rescue CDs to make
sure they are doing the right thing?  I'm particularly concerned about
PPC as we've never generated rescueCDs for PPC (and I wrote some of the
code so there is guaranteed to be some bugs (;  )
