The pull request is https://github.com/beagleboard/kernel/pull/33

Should be easy to keep those in sync as you control the s/w going
out on all the new BeagleBones. The type of people that have early
boards can all handle s/w changes like this otherwise they shouldn't
be in the alpha test group.

Anything else that prevents us from fixing this fdtfile hunk now?
