How do you align the array with the 64/128 byte flash sector 
boundries?

I'm doing the same thing as the original poster.  I tried intially 
to create a memory section in flash and use the linker to place it 
in memory.  I abandoned doing that because I couldn't debug my code
easily because AVR Studio doesn't handle extra memory sections
properly.  (As of build 472, supposedly fixed next release?)

Currently I use defines to set the start and end of the file system
and I manually check to make sure the code hasn't 'gone over'.
