Another question from the point of view of unifying things. What is
wrong with

        insmod kexec
                creates /dev/kexec (or kexecfs is you are Al Viro)
                hooks the reboot and panic final notifiers
        user copies file to /dev/kexec (which stuffs it into ram)

        reboot
                kexec module handler jumps to the first page of the
                kexec data in a defined state assuming its PIC

At which point we have clearly reduced kexec/oops reporter/lkcd/netdump
to a single common tiny interface.
