Terry Leatherwood has a Lana Lang who supports Clark in becoming Superman in his "Road Not Taken". I think that is the most sympathetic treatment of Lana you will ever find.
Actually, I take that back. Lana probably comes off even better in some ways in "The Man Under the Suite". Although since she is married before the story begins (not to Clark) she is never refered to as Lana Lang, but by here married name.
However on the whole I think Lana seems worse in fan fic than she did in Lois and Clark itself.
