[ODE] Still Spheres Vs Trimesh at Triangle Edges

If you really think your problem would be solved if there were no
sphere-edge collisions (I doubt it because then your spheres should sink on
trimesh convex edges), you can eighter implement the preprocessed mesh for
sphere collisions and submit it to svn (the more difficult way ;) or take
much easier and faster way: have a look on GetContactData in
collision_trimesh_sphere.cpp and comment out all edge collisions (all
branches except region 0 - interior).

Anyway, as I say I doubt this would be a good solution. What exactly is the
problem you are experiencing?
