Oh, and:

  if ($chip = 2) {
	# check for 'shadow' write-protect register at 0x30-37
	i2c_set_slave_addr($file,$addr - 0x20);
	if(i2c_smbus_write_quick($file,$SMBUS_WRITE) >= 0 &&
	   i2c_smbus_read_byte_data($file,0x80) = -1) {
		if($checksum = 0) {
			return (9, $addr - 0x20);
		} else {
			return (2, $addr - 0x20);
		}
	}
  }

Shouldn't you restore the original slave address before returning?
