Hi. I have the exact same intel card id (8086:0116), but my Dell is the n411z.
I am facing the same probelm with the latest ubuntu kernels i.e. my brightness function keys do not work with 13.10 and 14.04 (i.e. kernels 3.11 and 3.13). Whilst these keys worked perfectly till 13.04.

More info can be found here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1280394

Unfortunately even if I installed the latest permitted BIOS by DELL for my laptop (A06), there is no option for "legacy rom" that I can enable and see if that will fix the problem.

I tried various boot parameters but none worked. The brightness function keys do not even produce any results in acpi_listen.

Do you have any ideas how to fix it? Any help would be very much appreciated. Thank you.
