Nak - this isn't the kernel, this is a separate program, namely the
bootwrapper that decompresses the kernel image, and it has its own
printf (not printk) implementation in arch/powerpc/boot/stdio.c, which
doesn't understand the %pX extensions (and I don't see any good reason
to make it do so).

Paul.
