binary dumping a 24LC64 i2c eeprom by sniffing reads

I was gifted an old USB to compact flash adaptor recently. Inside, it's based around a SL11RIDE USB to ATA chip, a T14L256 SRAM chip and a 25LC64 i2c serial eeprom. I've been wanting to have a play with the buspirate's i2c sniffer for a while and the 'vendor/device configuration' stored in the eeprom sounded like a good first target.

Capturing the data from the buspirate is pretty trivial and really just comes down to connecting SCL/SDA/GND to the eeprom, setting the mode to i2c and starting the sniffer macro
