I can currently use the initramfs-live-boot functionality to generate a .cpio.gz file, but I am lost on how to get this to 'bundle' with the uImage.

if you add 

INITRAMFS_IMAGE_BUNDLE = "1"
INITRAMFS_IMAGE = "<name of your initramfs-image>"

in you local.conf that should help it to create uImage with everything
in it.
