When reporting this bug, I called it a regression because an older kernel package worked, but a more recent one did not. I did not realize that the older one was mainline, and the later one with Ubuntu patches.
The system runs Ubuntu raring. Since raring comes with a 3.8, which I believe does not fully support the DL-195, I installed a 3.11 kernel from Saucy (but nothing else). When at some later point I updated to a more recent Saucy kernel (apparently this time including Ubuntu patches), things stopped working.
So yes, I would say it's possible that this has never worked in Ubuntu but only in mainline.
