I don't think that'll give me enough space. I'll try it, though. My 64-bit
kernel payload is 874K right now.   

I was hoping that there was a way that I could make LinuxBIOS think there
was a full fallback image, but just have the code to jump to the normal
image included.

I can kexec a 64-bit kernel from a 32-bit kernel.  I haven't been successful
with kexec from a 64-bit kernel to another 64-bit kernel.  It may be because
the stripped down version of kexec that I'm using from olpc is too
stripped-down.
