In my Aboriginal Linux project (http://landley.net/aboriginal) I have a
config that builds a ppc440 cross compiler and builds a root filesystem
and kernel with it, but the kernel .config is bog standard 32 bit PPC
(mac99 board I think). It boots and runs, gives you a shell prompt, but
occasionally misbehaves you try to do anything fancy with it.
Last I checked, the bamboo board was implemented for KVM not QEMU, and
QEMU didn't have a ppc440 processor emulation. But that was over a year
ago, things could easily have changed...
What kernel .config are you using for the bamboo kernel?
