I am at present wondering about an alternative, based on re-considering my use of eeprom: continue (evidently) to use eeprom for storing data that must survive boots, but rather than initialising the eeprom contents by download, define a condition which triggers initialisation of the contents of eeprom by program-controlled transfer from flash (for instance, trigger the transfer when at boot-time a specific eeprom byte contains 0xFF). That would allow to always maintain the EESAVE bit programmed and keep my private data in some "reserved corner" of eeprom. My application could probably live with such an approach - still needs some thinking about.
