I figured a lot of people are on both lists, but it was getting a bit  
tough to follow.  Anyway, the headers create #defines that create  
sections for the fuses and lock bits.  To get everything working with  
AVRdude today, there is some "magic" in the avr-gcc.mk rules file  
that uses binutils to find all the sections (other than text, data,  
bss, etc) in the binary and split them into separate .hex files.   
Then, the avrdude.mk rules know to look for those files during the  
program target.  Having avrdude support ELF directly would reduce the  
complexity of the makefiles a bit, but it isn't absolutely necessary.
