The reason for commenting out the code is the 1MiB size constraint. The
assumption was that the OLPC BIOS would only boot Linux kernel's.

You're free using the original kexec-tools from buildrom/packages/ which
supports static ELF binaries (memtest86 is supposed to boot via kexec,
though I haven't tried it myself).
