Wow - one really does have to keep one's finger on the pulse with this jQuery business. Since Part One of this post there have been not one but three further releases of jQuery, so the current version is now 1.2.6. And I am happy to report that since then I have gotten involved in the effort to bring the jQuery Update module up to date, which entails not only trying to keep up with this moving target but also ironing out the bugs that have been popping up in all sorts of unexpected places due to the major API changes that came with version 1.2.
