Narcissus and the bone

I used narcissus to create a beaglebone image. I expected to find boot/MLO and boot/u-boot-*.bin, but they weren’t there. Is this a narcissus bug or am I not using it right? \

I tried replacing the missing files with files I found here http://www.angstrom-distribution.org/demo/beaglebone/, but the bone doesn’t boot.

Any help/tips/pointers greatly appreciated.
