using 'objdump -D' on the two binaries, then diff'ing the output might
help.  zImage is created from some ELF file in the build process.  Might
need to use this ELF file instead of zImage.  or gunzip zImage before
running objdump.

If you put both zImage files online, and send a link, people could have
a look at it.

cheers,

David
