Let's put aside brightness problem. this is not a support forum. We should not flood here. You may open a tread in the forum.
Regarding long time. I think that realistic estimation may be end of April 2014, when 15.04 is released and a new kernel will be used there. At the same time, or about the same kernel will ne offered in official repos for 1404 LTS.
Unless Canonical team accepts a patch for 3.16 kernel.
Procedure includes following steps:
1. Acceptance of Mathias patch by Linux kernel team. I hope it will be in upstream 3.18 version. Or in 3.19.
2. Backport of this patch for 3.16 kernel (optional). I will do waht I can and prepare the patch.
3. Testing in "proposed" and release in main repos.

Optimistic 2-3 months, realistic 5 months...
You can help by testing, I guess.
