Martin Beltov (mbeltov) wrote : include samsung-backlight fix in main kernel

Hello, dear developers of Ubuntu! I want to ask something, that I think is relevant to the Ubuntu:
I have a small samsung netbook that requires a custom kernel module to be installed from a ppa (https://launchpad.net/~voria/+archive/ppa) so that fn keys work for backlight brightness adjustment. My question is: can this kernel module and script be installed in the main kernel, so that this annoyance can be avoided? From what I read this is an issue that has plagued samsung laptop owners for several years now. The installed samsung-tools and samsung-backlight fixes this issue.
I am willing to help if I can, I just want to have a truly out-of-the-box experience with Gnu/Linux. This problem is present in all distros (that's what I read from the Internet, I have only tried it on *buntu).
Thank you in advance.
