If you have source code for the gyro board, you could modify it to use RS232, assuming there are appropriate free pins to use. There are a lot of restrictions on which pins you can use for which purpose on Arduino. Software serial ports must be on pins that can generate I/O interrupts. It is certainly possible to do bit-banged I2C on the KFlop, provided the bit rate is low enough, but I'd expect you would have to write the driver yourself. Not that it's that difficult - I2C is pretty simple. And I'm sure you could easily find some C code on the net to start with. The challenge would be in dealing with the task timing on KFlop.

The Arduino also has up to four hardware serial ports. You'd be better off using one of those, if the pins are available on your board. Look at the Arduino SerialPort device class. The hardware ports are a total no-brainer to use.
