Actually I am not sure where did 896MB magic value had come from for x86_64 so far. I assumed that it was some kexec-tools limitation so first trying 896MB will preserve working with old kexec-tools. If it was some kernel limitation, then I agree it should not be required anymore. I do remember that old pugatory had 2G limit. So may be we can first try reserve with-in first 2G, then with-in first 4G and then above 4G. (Assuming 896M was not kexec-tools limitation and had something to do with kernel/initramfs).
