Both.  I am to build the system as soon as possible, and it needs to have
tolerable performance running a CPU simulator (which I am told is

At least one person has told me that I must use a PPC64 kernel to boot at all
on a G5.

I don't know what you mean by asserting that the G5 is 128-bits.  The most
relevant features (default ALU size and address space) are both 64, which I
assume is the distinction made between ppc and ppc64.  That said, this is a
machine with under 4G of memory (had to compromise somewhere), so I can
probably get away with plain-old, if it's supposed to run at all.

You can run the installer from the rescue CD?  Cool.

Well, yes.  And the G5 is a PPC970; in this case, a pair of PPC970FX.

I will try just about anything, but I was hoping that someone had actually
run one of these and could confirm that it would run; downloads are running
about a day per ISO set, and I was supposed to be running this on Monday at
the latest, or ideally about three days before they told me about the
