[BProc] swapping kmonte with kexec

[Joshua A. <lu...@ln...>]

I have some working test patches to beoboot that swaps out kmonte with
kexec.  So far I have booted one node using it and would love some
further testing.

Benefits to kexec:
 more arch support (works with x86_64 on stage1!)
 is now in the kernel
 works with smp kernels

This has allowed me to use a single kernel build for both stage1 and
stage2 images (yay!).

These patches depend on mkelfImage and a statically build kexec binary.

If you are interested, let me know.  I'd post them but they will
probably be changing over the next little while as I start cleaning them
up.
