I bet its a Spansion S25FL064PIF flash chip, but that's just guessing off the part number you gave.
I've never seen an Ardiuno based eeprom programmer, it's possible I just don't think anyone's ever wrote one for our purpose, plus you would need more than 9600buad serial to do it in any reasonable amount of time... dumping 8MB of flash @ 9600buad would take 2 hours, even 115200 buad would take 10 minuets or so and I'm not even sure of the clocks are fast enough to read/write a SPI flash chip @ that speed on an Ardiuno. The closest thing I know of is the FlashcatUSB that uses the Atmega32U2
