Well, the bootloader is a plain AVR910 one, so you could probably
simply read it out again.  Also, you could sniff the serial
communication.  You might look whether there's already a tool to
convert ebn files to hex...

Finally, there's at least one modified firmware around on
avrfreaks.net where someone modified the disassembled firmware to run
on the ATmega169 of an AVR Butterfly.
