we are not enabling extlinux here right now because of how we have to do partitioning. though it is a solvable problem. Because the MLO only reads from fat we have a 20M fat partition that holds MLO u-boot.img and a uEnv.txt file. what I really want to do is teach the MLO to load u-boot.img from either ext2 or fat and use raw space for the MLO so then we can just go to standard partitioning.
