The qemu-system-ppc emulator for Xilinx ML507 doesn't work with uImage. It only works with vmlinux at the moment. 

Is there a way to modify yocto to generate a vmlinux image? 

If I specify KERNEL_IMAGETYPE="vmlinux" gives the following errors during compilation, also giving me a warning that I may need to install module-init-tools. Is this necessary to generate a vmlinux image, and if so where do I specify it's inclusion?
