Interesting...
As a somewhat quick sanity check, if you build BusyBox 1.17.3 and
apply the proper patches from that generation of the embedded book, do
you get the same operation?

Apply both the fixes and config patches at the beginning of the
BusyBox build, section 7.4.  As I have output from a successful boot
with this version, that might be a good sanity check.

Downloads you'll need:
http://busybox.net/downloads/busybox-1.17.3.tar.bz2
http://svn.cross-lfs.org/svn/repos/patches/busybox/busybox-1.17.3-fixes-1.patch
http://svn.cross-lfs.org/svn/repos/patches/busybox/busybox-1.17.3-config-1.patch

If you grab a copy of the git repo for the embedded book, you can
checkout commit 1b109e6eae092a7a1fe4a5580683e93507fa7e02 to get the
old instructions at the last point where BusyBox was version 1.17.3.
