And if you use a 3-axis gyro, and 2 more 3-axis accelerometers arranged non-colinear with the first, combined with an acceleration estimating algorithm based on absolute position measurements, then you might actually get the info during turns as well, as long as you take a little care to eliminate the magnetic contributions from any major power lines by using twisted pairs and not placing your magnetometer on a circuit board with a ground or power plane.

Although differentiating absolute position from a GPS at 1 second intervals can result in some pretty jumpy accelerations!
