...that was indeed a problem. I can do successful kexec, as long as I
load bzImage (and not vmlinux). (Both kernels 2.6.22 and
2.6.23-rc2-git). Problem is, I can only load bzImage using -l, attempt
to load bzImage using -p results in 

"Could not find a free area of memory of 9000 bytes"
locate_hole failed

. Any ideas?
