The kexec-tools-testing-20061214 does not work for SN platform. I just pull down your git tree. Yeah, at least the load_crashdump_segments() routine does not have the patch Nan-hai posted last year to make kexec-tools working in SN. I remembered there were at least three patches needed for SN. I will compare those patches against your git tree and see if those were the only things we need.
