Can you zip up your build directory and e-mail it to me? Also, make sure you've plugged the gyro into channel one. If you plug it into a different channel than specified in gyro.h, the ADC can still read residual charge from the sample-and-hold capacitor if that input is floating. How is the gyro wired? Perhaps it's output driver is weak and having a tough time driving the capacitance of the cabling? Ideally, the cable should be as short as possible.
