Bah. Here's what you do: Take the wheels off the bike, put the fork between the rungs of a ladder, and pull on the back of the bike to straighten your fork. If you apply the force at the rear of the bike frame, your force is magnified (less force required by you, therefore it is very controlled). I did this on a '84 Nishiki and got the fork pretty much back to perfect geometry, and it was worse than yours (I couldn't steer past the downtube). I rode it like that for 6 months until I got a new bike. If that's a steel fork, it won't fail. You still need to replace it, but it should be fine to ride temporarily.
EDIT: What I'm suggesting is essentially the same as what fietsbob said, only with more control over the forces applied.
