bzImage is not a cpio-archive. It's the result of linking a gzip-ed
version of the kernel and some uncompression and boot code. See the end
of the kernel compilation process for info:

  LD      vmlinux
  SYSMAP  System.map
  SYSMAP  .tmp_System.map
  CC      arch/x86/boot/version.o
  LD      arch/x86/boot/setup.elf
  OBJCOPY arch/x86/boot/setup.bin
  OBJCOPY arch/x86/boot/compressed/vmlinux.bin
  GZIP    arch/x86/boot/compressed/vmlinux.bin.gz
  LD      arch/x86/boot/compressed/piggy.o
  LD      arch/x86/boot/compressed/vmlinux
  OBJCOPY arch/x86/boot/vmlinux.bin
  BUILD   arch/x86/boot/bzImage

Sincerly,

Thomas
