Slow down with the drilling. Step away from the power tools. Thanks guys- you scared me into finding a solution.

Found it-
they call it a clamp on Front derailleur cable stop. Didn't know that Suntour superbe pro made 2 versions, one with the cable stop and one without.
Naturally the one without a cable stop is more available. On lots of 70's-80's bikes they have above bracket cable routing.
this bike has a brazed on routing guide- http://phred.org/~alex/pictures/bikes/trekroad/bb2.jpg
