[ODE] converting opengl matrices to ODE positions. or something!

That's where the padding goes for the rotation matrix -- it's padded to 
multiples of 4 floats (as described in the docs).

Regarding scaling, you can do whatever you want to the matrix after 
getting it. If you want to scale the object, but not the position, then 
only scale GL matrix indices 0..11; if you want to scale the entire 
world, then scale all of the values.
