Hi Ilia, Ben,
I gave a shot at drm-next as of the following commit:

I have been running that kernel for a large part of a work day, and, so
far, it has worked pretty well.
Many thanks!
Below are a couple remaining issues, none of which are blocking in my
case (GeForce 9400/DP/Dell U2711), but which may be worth investigating
if they also happen with other hardware combinations:
1. The display does not wake up from (timed-out or forced) sleep on
keypress or mouse move as it used to. Activating the OSD menu wakes
up the panel; Nouveau seems to pick that up as a hint to get going;
2. The panel's backlight flickers very noticeably after a soft power
cycle. It also flickers, but less noticeably, after a hard unplug/
re-plug. Force-switching to an unconnected input source and back
makes it stable again.
Let me know if there's any way I can assist you further. In the
meantime, thanks again—it seems I'm not stuck with 3.8 anymore!
Cheers, -D</pre>
