Carefully crafting the contents of the 32KB EEPROM image, and then writing it into the appropriate device handle followed by a reboot yields this result...
Despite the horribly slow EEPROM write cycle, this procedure is really quite painless. The prototype "cape" as it currently stands is literally just a bog-standard Microchip 24LC256 EEPROM attached to pins 19 and 20 on the BBB. That is not even the EEPROM that is suggested in the BBB's SRM. I guess one generic 32KB I2C EEPROM device is as good as any other (as my Great-Grandfather used to say).
