Have you looked at the Honeywell HMC2003 triaxial magnetometer?

Some links on the net showing how to use it in several applications, but I
only remember this one:

http://npsnet.org/~bachmann/Papers/dissertation.pdf

this is a whole 6DOF made from the triple magnetometer, ADXL's and Murata
gyrostar piezo gyros.

Alvaro.
