Grrr...
Put the lens on my 400D and it works fine. I guess I have never noticed the problem before as my only truly wide-aperture lens is my 50mm and that's broke. So most of the time I am shooting at f/4 or smaller.
So I guess that takes me to a new logical question...
Was the 10D known for poor focussing performance on low contrast subjects or am I looking at a faulty body?
