[Intel-gfx] Status of native backlight patchset?

[Michel Alexandre Salim]

Hi,

Is there an updated version of the native backlight patchset that 
Matthew posted in November?

http://thread.gmane.org/gmane.linux.acpi.devel/48145

On my Sony Vaio Y, Intel Ironlake/Arrandale integrated graphics, I'm 
having problems setting my backlight level through 
/sys/class/backlight/acpi_video0 -- all inputs seem to be ignored:

https://bugs.freedesktop.org/show_bug.cgi?id=34417

and it looks like the same issue that is being tracked by Ubuntu's Kamal 
Mostafa, based on Matthew's patchset:

https://launchpad.net/~kamalmostafa/+archive/linux-kamal-mjgbacklight

I've not been able to find a patchset newer than the one from November,
and if I apply patches 1 & 2 (skipping 3 & 4 because they don't apply to 
i915), I get a kernel with broken KMS. Should I apply #5 as well? I'll 
wait to see if there's a newer patchset before trying that, though.

Matthew, do you have a public kernel git tree I can clone from?

Thanks,
