I take the latest EOS nightly and extract all the files located in boot.img. From those files I get the kernel. There are a few other modules from the ROM itself that I grabbed as well just to make sure everything was up-to-date. Then I just swap them out with the older files in an older kernel .zip. Then share the kernel magic with you guys. I'd provide a changlog but it appears those haven't been generating with the latest nightlies.
EDIT: My mistake, the changelog issue is for wifi-only xooms. 4G has recent changelogs.
