@Mortimer - i think I would concur with your findings, although I didn't test so extensively.

A mains PSU connect to the RPi power inlet was required to keep the low Voltage warning from appearing.
One word of warning to others - IF you do this, remember NOT to power the Lapdock with it's own power supply at the same time as powering the RPi from another adaptor. I forgot and did this once when the Lapdock battery was getting low. BAD mistake. The first time I blew a hole in the Microcontroller of the Atrix and let the blue smoke out. The second
time I smacked myself around the head a few times for being so stupid!
No visible effect this time, but the result was the same. It's easily done. Maybe powering the RPi by a suitable battery powerbank instead of an adaptor would be a better solution if you think you might do this by accident.

same keyboard issue here, so drop it to closet 2 or 3 years ago, poor Atrix
Yes, the keyboard reliability is a real shame, but it can still be used with an external USB keyboard, but it sort of defeats some of the purpose of having the lapdock.
