Well, the bolt really is aluminum. Actually, the only other 1R that I have also had an aluminum quill bolt when new, but I replaced that one with a steel bolt. Maybe an unnecessary precaution, because I know plenty of people have used these for years without problems -- Chuck Schmidt among them, according to the archives.
This is probably a good place to remind listers about Jack Bissell's Cinelli
stem and bars timeline at: http://www.43bikes.com/
An excellent resource. Thanks, Jack. Interestingly, the stem in question had the earlier "Cinelli" face plate, but it did have an aluminum quill bolt.
I may not be able to save the stem body if drilling doesn't go as smoothly as I plan, but at least I'll have some 1R spare parts. The stem is about 2cm too short for me and not particularly pristine, so I can live without it.
Any other strategies would be appreciated, though.

Tap away but you might be tempted to use the biggest maul available :-) If it is really an alloy bolt it could bend fairly easily. That would be really messy.
