Can you try booting the daily builds ? These are at :http://people.debian.org/~luther/d-i/images/daily/powerpc64/netboot64/ or : http://people.debian.org/~luther/d-i/images/daily/powerpc64/cdrom64/ Get the initrd.gz and vmlinux on a cd or tftp boot server, write the adequate yaboot.conf, and try them out.
So, I download both files, put them in the install/power4 directory of the cd image I already have and then I create a bootable CD. Is that right? I don't know how to create a bootable CD, I hope I find a howto on that for powerpc.
I guess I will have to use -G for mkisofs before I rebuild the cd image ... (help on that is appreciated)
Thanks! At least now I have something to try. And yes, I will let you know the outcome.
Eduardo.
