I would focus on kexec -e first and you don't need those two options. I suspect those two things should work but I would have to look and see why they are not selectable.

First off, what SHA of the kernel are you using? It looks like 2.6.35 should have the patches you need, but I want to double check. Also, how did you compile kexec-tools? Cross compile? What compiler are you using?
