If I read arch/sparc/boot/Makefile correctly then the sparc64 image _is_ stripped as the zImage target calls $(obj)/image which does the strip. So the difference is less than you suggest. > Could we agree on the _same_ format for zImage on sparc and sparc64 and > then apply that patch? I vaguely recall from Debian work that loading compressed kernels caused problems on sparc32 hardware (due to insufficient memory?), which could justify the difference. But I may be wrong.
