This works with buildrom for several targets.  AMD Serengeti Cheetah is one
place to look.  If you configure it for LAB (Linux As Bootloader) x86_64, it
will build a kernel and an initrd, then use mkelfImage and put it all

It will also set up the Config.lb file correctly to save space (fallback

The caveat is that something broke for me when I upgraded to Fedora Core 6,
and it won't boot all the way.  Fedora Core 5 works fine.  Other distros?
