PPC440 emulation support has only been added to Qemu very recently (0.14). So far, the only board that is somewhat known to work is the virtex5 ml507 one with a 440x5 xilinx cpu. Please see http://wiki.qemu.org/ChangeLog/0.14#PPC for details.

The bamboo board was added to enable KVM support for 440, it hasn't been used with the emulation target yet.

What exactly are you trying to emulate?
