This looks like the kernel dies very early during the boot.

Yes I think you have the wrong kernel installed. Try to install
linux-image-2.6-powerpc64. Try "aptitude install
linux-image-2.6-powerpc64" after booting into rescue mode and mounting
/proc and /sys (see below).

The proc filesystem is not mounted inside the rescue chroot. You can
mount it with "mount -t proc none /proc". You probably also need to
mount sysfs before installing the kernel (mount -t sysfs none /sys).
