Which RS6000 model is this ? a PReP one or a CHRP one ?

You should have mkvmlinuz installed, and it should have produced a
/boot/vmlinuz kernel, which you can dd to the PReP partition.
I guess though that you don't use the debian kernel but your own. In
this case, remember us why you are not using the debian kernel, and
maybe file a bug report about this issue if it didn't work for you ?
If it is a CHRP box, you could install yaboot and move the yaboot
executable onto your PReP partition.

You copied the vmlinux kernel, right ? This one is the plain elf kernel,
what you need is the vmlinuz, which includes a small chrp or prep boot
wrapper.

not really. We need more information about your setup though to help you
more clearly.
