I tried this, and it works:

// jmp 0xC00
asm volatile (".word 0x940E");
asm volatile (".word 0x0C00");

Separately, I changed the linker script avr4.x from:
  .eeprom  :
        AT (ADDR (.text) + SIZEOF (.text) + SIZEOF (.data))

to:
        AT (ADDR (.text) + 8*1024 + SIZEOF (.data))

This gets rid of the overlapping sections by pushing the position of the 
 .eeprom section past the size of the Flash.  I didn't really like this 
solution, because I have little knowledge of the linker scripts, and I 
don't want to break anything.  Perhaps someone with more knowledge than 
I can change the linker scripts for the next release.  Or, perhaps they 
are fine the way they are...

Thanks for everyone's suggestions,
Louis Beaudoin
