Apparently the hardware itself is fairly new, the 4.3 kernel still
required i915.preliminary_hw_support=1. 4.4 does not, but rc6 is still
not working, etc. See
https://wiki.archlinux.org/index.php/Intel_graphics#Skylake_Support

I guess eventually it will be fixed. Now I understand that it has
nothing to do with Mplayer, and I have a workaround (-vo gl actually has
the lowest power consumption).

I would like to thank everyone for the help.

best,
