Maybe, part of your modifications are not necessary: root.gz is always
loaded in RAM. If you explore in /etc/rc you will find a "mount_usr".
If you pass to the kernel the parameter usr=/dev/XYZ, mulinux try to
mount boot/usr.img in /usr (boot/ is a directory on /dev/XYZ).

This is a limitation of the 2.0.* serie.

I suggest you to use the script "roclone" (read-only clone) trying to
get back the "three" files.
