I would start with:

do_action('add_meta_boxes', $post_type, $post);
do_action('add_meta_boxes_' . $post_type, $post);

As of right now, it's a bit of a crapshoot.

$typenow was added in 3.0 I think. Regardless, yes, $current_screen is far
more powerful than $pagenow.

before init and admin_init?  It would seem that information like current
post type, post ID, taxonomy etc are exactly the types of information that
should be available in init/admin_init?

Re: compelling reason, not really. See also the ticket above. I wouldn't
mind restructuring things in there to make things more consistent.
