Default Dockingport Pinout

Hello there

With ICS on my Folio i am very very happy --- it just runs.

But one think i hate. My battery ist empty just when the charging cable is not in my room.
The nicest One could be loading like the WebOS Devices with the Touchstone.
But I think this is not possible. So my question is: Did anybody have the pinout for the docking port so i could build a stand (or maybe two or three) to just put them there?

Thanks for help
