(Get the code!)
From earlier on #ubuntu-x IRC in case it is helpful:
2:05 PM <alex_mayorga> bryceh: Got powers on https:/
2:05 PM <ubottu> bugzilla.kernel.org bug 41652 in Power-Other "Brightness control keys not working" [Normal,Needinfo]
2:07 PM <bryceh> patchset proposed on platform-driver-x86 via http://<email address hidden>
2:07 PM <alex_mayorga> How come the keys are caught, OSD shows, but in the end nothing happens?
2:10 PM <alex_mayorga> Guess kernel devs don't care as long as their mac book pros work, right? ;-P
2:11 PM <hyperair> maybe kernel hackers just don't buy vaios.
2:11 PM <mlankhorst> pretty much..
2:11 PM • hyperair wouldn't either.
2:12 PM • alex_mayorga doesn't have much sayin on what he gets for "saturnalia"
2:13 PM <bryceh> http://<email address hidden>
2:13 PM <bryceh> Added support for handle 0x0143 (Vaio SA/SB/SC, CA/CB). Minor corrections included.
2:13 PM <bryceh> guess that doesn't fix vaoi vpccw though
2:17 PM <alex_mayorga> bryceh: the patched were never taken, were they?
2:18 PM <alex_mayorga> The guy seems to have a Launchpad account https:/
2:18 PM <bryceh> alex_mayorga, doesn't appear so to me
2:24 PM <alex_mayorga> What is there to do then? Upstream doesn't seem to care =(
2:25 PM <mlankhorst> it's not cc'd to lkml..
2:26 PM <bryceh> mlankhorst, yeah, presumably because he wanted to finish the v2 set of patches first? I'm not really familiar with the platform-driver-x86 list.
2:28 PM <bryceh> alex_mayorga, as far as next steps, some random ideas...
2:28 PM <mlankhorst> reading that mail-archive, there were some technical problems with that patch anyhow..
2:30 PM <bryceh> alex_mayorga, 1. contact the patch author, Marco Chiappero, to get an update about the patch and if he plans to re-propose it. (And if he can update it to include your model).
2:31 PM <bryceh> alex_mayorga, 2. try sweet talking the ubuntu kernel team into building a kernel with that patchset for you to test. This might not be possible though, if there's problems with the kernel or if it's hard to figure out how to apply it to a mainline kernel.
2:32 PM <bryceh> alex_mayorga, 3. If you feel like hacking on some C code, see if you can figure out which chunk from all those patches provide the backlight fix, extract it and revise it to work with the current kernel, and then verify that bit alone fixes it for you. If so, then propose inclusion of that into the kernel.
2:32 PM <bryceh> that last one could be rather labor intensive
2:34 PM <bryceh> alex_mayorga, 4. join the platform-driver-x86 mailing list, and post an email asking for an update on the status of Marco's vaio patchset
2:34 PM <bryceh> alex_mayorga, meanwhile, I've added my findings to the bug reports and tagged them to get some attention from our kernel team. However I think they'll be more likely to take action if one of the above steps is taken.
