Another solution to your problem, without going through the hassle of 
patching and rebuilding Binutils, is the SRecord utilities on SF:
<http://sourceforge.net/projects/srecord>
SRecord can manipulate load files of many different formats, including 
of course SRecord. IIRC, it can do the kind of reformatting that you 
want. SRecord is licensed under GPL and is known to build and work on 
GNU/Linux and Windows.
