I looks like it is trying to boot a zImage, which the legacy
bootloader can't handle.

There are two things you need do to to make it work.  One is to get vmlinux
or vmlinux.strip somewhere the bootloader can load it from, and two, is to
make a proper kboot command to load that file.

For the first, at the kboot prompt, type this

  kboot: ls -l //mnt/root/boot

Note the double slashes.  You need to see the newly installed vmlinux there.
If it is not there, or an old file is there ,you need to modify
scripts/package/mkspec, or manually copy the file there after the install.

Once that is working, then try this:

  kboot: echo $testing

or

 kboot: cat //mnt/root/etc/kboot.conf

It sould have vmlinux or vmlinux.strip.  My guess is that it will not, and
will be zImage.ps3.  You need to make a new menu item that is correct.
