    You guys are reinventing the wheel a lot at the moment and I'm in the
    middle of doing it for x86_64 lowlevel code :> Can we see if we can work
    a little more closely - perhaps we can get some shared code going that
    will allow us to handle these issues without stepping on each others'
    feet? In particular, shared code for

    - initramfs and initrd support
    - lowlevel suspend & resume

    would be good, wouldn't it?

    I'm tempted to add setting and checking signatures, but I'm also in the
    middle of implementing support for writing the image to a file, so that
    could get messy.

    Regards,

    Nigel
