This seems to be a misunderstanding of how C pointers work!
As described the pointer would point to a word not a byte.
By definition an address for the AVR is 16 bits and so pointers are also 16
bits unless otherwise forced.
I am able with the current tools to access all the eeprom in a mega128 QED

Details:
Shouldn't be the address of the eeprom access functions a 16bit integer?
e.g.:
uint8_t eeprom_read_byte (const uint16_t *addr);
void eeprom_write_byte (uint16_t *addr, uint8_t val);
How can I read a byte of the eeprom with an address higher than 255?
