Just use the smoothed normal as input the the bump_map() function. It 
should be perturbed just like any other normal. If the normals line up 
seamlessly before being perturbed, they should remain seamless 
afterwards. Of course, the perturbing pattern itself will be evaluated 
over the flat surface of the triangle, which can probably give visible 
effects in some odd cases, but my feeling is that this will be rare.
I'm not sure what averaging you're speaking of, or how it could undo 
smoothing. It should "just work".
BTW, where is the code that does this?
