The Poky and Angstrom kernels are equal, so there won't be any difference as far as I know. I simply like Poky more because of the simple way to setup a build environment. It's already preconfigured, and worked for me out of the box, unlike Angstrom.
Is it time already for a step by step installation guide then? I have it all set up all the way to the base system including networking. Most of the boot-errors are gone, for what it's worth. I know you are working on a huge all in one Debian guide ZDevil, but maybe I'll start a separate thread for a dedicated EABI Debian, since I have it all documented anyway. It took me a lot of time to figure out all the tweaks and configuration steps, so maybe a few of you can take advantage of that and make a quick start.
