I have not tried this yet but I need to put my binary data on fixed 
location too. (It will eventually be calculatated for each device during 
production, and the address cannot change each time a bug in the.. eeh a 
new feature is added to the software). As long as this data will be put 
at the end of the flash I don't think it is a problem. There are some 
switches with avr-objcopy that will set the start-address. However the 
other segments will not be moved, so if they overlap the linker will 
give an error.

look in the "Including a binary file as resource" thread
