This PCI id corresponds to Sandy Bridge and was not removed: all gen 6/7
were kept.

Do you have any sporadic GPU hang to report?

You can run glxgears in non-synchronized mode to check it:

$ vblank_mode=0 glxgears

Could you add a comment in the following table?

FIY, when it comes to my Thinkpads hot keys are managed in Linux by evdev
and are otherwise totally ignored since OI does not support it (for
instance you can check with xev) so xmodmap would not even help.

xf86-video-intel provides a backlight tool but I have not used it.
