Dariusz,
I tried your kernel + updated intel drivers with a MST Hub connected to
my Dell XPS 13 (Intel® HD graphics 5000).
Both monitors continued to be mirrors of each other, and I could not see
the two monitors in Ubuntu Display's settings or in xrandr.

I am very time constrained at the moment so I was not able to build David
Airlie's branch to test.
