TeX does it at three levels
 - with patterns, for 80-90% of words
 - a list of explicit exceptions compiled in
 - a per-document set of exceptions

well, I take it back. I had not remember that in DSSSL. I bet it isnt
implemented

have a look at the TeX Book, it'll point you at the research by Knuth
and Liang

hyphenating with a dictionary is slow, yes.
