They seem to work OK for me. How do you know what the x, y and z components should be?
If I remember correctly, there *is* a change in "handedness" of coordinate systems somewhere, but the code in the archives should compensate for this. There are examples of the quaternion code being used here: http://www.dscho.co.uk/blitz/tutorials/quaternions.shtml if you want to make sure you're using them correctly.
