> I just did a checkout of 96ae7a3a2d38b96c1dfee57fda2c2eaab7e9e762 and then cherry-picked this one. […]

Done

PS1:
> Maybe try to do something similar to CB:39708 on the X200.

Done

PS1:
> The button on the side is also still broken, though Fn+F9 does work

Done

PS1: 
This change should fix the redocking being broken. I have pushed another change (CB:51123) for fixing the undocking after resume, which also seems to fix the undock button on the left side of the dock.

TESTED on Lenovo X200
