Hi Peter,

actually I only doubt about exactly position of this headers - I mean
meguess it better should be _before_ "_end" not after. Since the others
script uses (acpi/wakeup_rm.S):

	wakeup_code_start:
	.incbin	"arch/x86/kernel/acpi/realmode/wakeup.bin"
	wakeup_code_end:

and kernel uses these wakeup_code_* marks to save/restore memory I think
it should be like

	. = HEADER_OFFSET;
	.header : {
		...
	}
	. = ALIGN(16);
	_end = .;
	/DISCARD/ ...
