-	Sometimes the LIS302 in N900 gets massive offset on one or more axes, due to unknown reason (possibly I2C errors). Symptoms: Dialer autorotation fails or gets weird. Even rebooting seems not to help to fix this, but removing battery for some seconds resets the chip. Powering down the device should help too (NB device never really powers down as long as power is on USB, i.e. charging)	+	Sometimes the LIS302 in N900 gets massive offset on one or more axes, due to unknown reason (possibly I2C errors).
