Yes, you got the general idea. 

And that's the way I would prefer to do it
(making only one last cut from the sphere),
but I haven't figured out the detailed CSG 
for that yet! :)

(For me it seemed a bit complicated, because 
the top of the cone has to be tangential to 
the sphere. An because of that I was afraid 
that the cone would leave some tiny leftovers 
near the edges of the bump.)

I posted my code to the povray.text.scene-files
news group. 

(My bumps are placed in the middle of the 
pentagons and hexagons of a Buckminsterfullerene.
And because I was to lazy to calculate the 
positions of the bumps and then paste them into 
the source code, you will also find the 
co-ordinates for a whole such "Buckyball" in 
there.)
