Thanks, done, using the git sources and the and debian/rules binary in
the package xserver-xorg-video-intel-2.99.916+git20141119 to build a
deb package.

Since the debian packaging seems to not introduce any variation apart
of a new utility (intel-virtual-output) I guess the following is fine:

grep -si 2.99 /var/log/Xorg.0.log
[    46.446]     compiled for 1.16.2.901, module version = 2.99.917
[    46.459] (II) intel(0): SNA compiled: xserver-xorg-video-intel
2:2.99.916+git20141119-1~exp1 (maximilian attems <hidden>)

Please correct me if I am wrong.

Unfortunately I do not have access to the monitor right now (will do
the test around Christmas), I see that the xrand output now shows
DP1-1 for the old DP2 and DP1-2 for the old DP-3 and DP1-3 for the old
DP-4:
