There are issues with putting large amounts of data in PROGMEM on the '2560 due to the near/far thing; I think you can only fill 25% of the program space with PROGMEM before it can't be accessed via the normal method (read_byte_near() - read_byte_far() is needed), and IIRC almost nothing is smart enough to handle that correctly.
