Used build.sh on both machines with cleaned out obj,dest,TOOLS, first rebuild
TOOLS and distribution. Then compiled a new kernel:

===> build.sh command: ./build.sh -u -N 1 -j 12 -x -U -m amd64 -O 
/u/NetBSD/arch/amd64/obj -D /u/Net
BSD/arch/amd64/dest -T /u/NetBSD/arch/amd64/TOOLS kernel=/var/home/ks/NBconf/U40
===> build.sh started: Thu Oct  1 18:17:48 MEST 2009

===> MACHINE:          amd64
===> MACHINE_ARCH:     x86_64
===> Build platform:   NetBSD 5.99.16 amd64

===> RELEASEDIR path:  /u/NetBSD/arch/amd64/obj/releasedir
===> makewrapper:      /u/NetBSD/arch/amd64/TOOLS/bin/nbmake-amd64

Build directory is /u/NetBSD/arch/amd64/obj/sys/arch/amd64/compile/U40

Elf file type is EXEC (Executable file)
Entry point 0xffffffff80100000
There are 1 program headers, starting at offset 64

Program Headers:
  Type           Offset             VirtAddr           PhysAddr
                 FileSiz            MemSiz              Flags  Align

And here's the readelf -l from the old kernel running now:

Just looked at the other older kernels lying around: All have two "LOAD"s,
like the running one...
