I want to add ELF support to avrdude --- right now it's necessary to split 
the program being loaded into multiple hex files and pass them as separate 
arguments to avrdude, which is more trouble than it really needs to be. 
The fraction of ELF that avrdude would need to understand in order to use 
the linker's output file directly is pretty small; it seems like it'd be 
a straightforward weekend project.

I'll see if I can write up a description of avr-gcc and binutils' 
specialization of the ELF format and post it here for comment.
