That is in fact the origin of the term. Check out the book Hackers, by Steven Levy (http://www.amazon.com/Hackers-Computer-Revolution-Steven-Lev...) and read up on how the Tech Model Railroad Club appreciated 'clever tricks' on how someone solved something, and it didn't necessarily have to be a 'technical hack' to warrant the phrase.

Another great text on the topic was written by Stallman: http://stallman.org/articles/on-hacking.html

"It didn't become easy—for practical purposes, using two chopsticks is completely superior. But precisely because using three in one hand is hard and ordinarily never thought of, it has 'hack value', as my lunch companions immediately recognized. Playfully doing something difficult, whether useful or not, that is hacking."
