MEGA2560 has SDA on digital pin 20 and SCL on digital pin 21. Whatever TWI interface is used for 'the default' needs to have its TWI pins mapped to 20 and 21 accordingly. This should be done for the xmega128A1 variant as well as any other variants that intend to be MEGA2560 compatible in their layout.

Mike's layout should handle this. The default layout will also.
