AFAIK, the holdup is not on our side but in the completion of jQuery
1.0, which is currently in testing.

I've used the patched jQuery with the patched copy of Drupal HEAD, and
things seem to work very smoothly. Whether we're in a position to push
forward before the 'final' version of jQuery is ready though... I'm not
sure.
