# GRUB refuses to use the addresses in the multiboot header if it
# finds a valid ELF header, so the dd hacks a zero into the high byte
# of the physical address field.  I tried using AT() in the linker
# script to properly generate separate physical and virtual
# addresses, but that caused the strip command to issue a warning and
# wipe out the BSS (setting memsz to filesz).
