I am actually *SURE* that the value was stable since I measured it on the oscilloscope and saw no artifacts. Also, the accelerometer's power comes from an I2C chip which is not affected by the microcontroller reset, and I turned it on before reseting the mote. It is hard trying with another voltage source since the circuit is smd, but if you think it is necessary I can try it with the tmote mini.
