After ongoing stability problems (i.e. freezes) with LUbuntu I switched to Bananian two weeks ago and the BPI is now running solid and stable.
Changing the power supply and SD card did not help the former behaviour in contrast to the change from LUbuntu to Bananian.
The Raspian and Lubuntu releases at http://www.lemaker.org/ are yet not supporting Tokenized Interface Identifiers.
I fixed a minor problem with the UFW in my Lubuntu installation a few minutes ago.
By relaying DNS queries to local dnsmasq instances, debugging DNS servers in newer Ubuntu releases is no longer strictly file-based.
I applied a classical (in the context of Debian) upgrade on my Linux Mint installation and even though Mint is not recommending this option (instead their favorite is a fresh install with restore). Nevertheless my system still works without drawbacks.
In general the Presenter R400 works fine, it’s immediately active after the USB receiver is plugged in and the keys representing Page Up/Down are working out of the box. Thus presentations in LibreOffice/OpenOffice, PDF Viewer (in my case Okular) and Google Docs are stepping forward and backwards using the main keys.
In contrast the smaller keys for jumping to presentation mode and disabling the display are sending codes, that the KDE desktop can’t process.

At least on Linux Mint Petra the mount of an SD card will not survive suspend mode.
You can query the Service Tag of Dell hardware quite easily:
Even if there are already IPv6-enabled mirrors, that help to maintain an IPv6-only Ubuntu installation, it’s a little tricky to apply a release upgrade.
