In collaborative work of Alexander Wirt, Marc Brockschmidt, Julien Danjou and me there is now a public list of packages which are in proposed-updates and await moderation currently.
The backlog in that queue is currently decreasing drastically, thanks to AJ. Builds of the new D-I for Sarge r3 should start as soon as all needed packages are now spread to all mirrors.
Update: Ooops, perhaps i should also add the link to that page.
