Hi,

I have the problem described in the thread here 
(https://lkml.org/lkml/2011/4/29/217) where the backlight
values are reversed so although stuff is displayed on the screen, the 
backlight is off. This occurs with kernels from about 2.6.39 onwards.

After booting a "broken" kernel (>~2.6.39), the backlight can be lit 
temporarily with:
setpci -s 00:02.0 F4.B=0
and then turned off with:
setpci -s 00:02.0 F4.B=FF

Yesterday I tried this patch, https://lkml.org/lkml/2011/4/30/37 by 
manually applying it to the 3.2.1
kernel source - this fixes the problem.

** Unfortunately the LKML thread stops after this patch and given that 
the problem is still present in the latest source, this code wasn't 
pushed into the kernel. Is there a reason for this or was it just 
forgotten about? What can I do about this? I am happy to make a git 
patch with the latest source if this will help.

If it is relevant, the backlight brightness controls (Fn-left, Fn-right) 
have never worked on any kernel
version, although they are picked up by acpi_listen.

The machine is a Packard Bell XS butterfly laptop, 11.6", 1.3GHz celeron 
743, 2gb ram, etc.
As per the posting guidelines, here is loads of info about it:

From: Linus Torvalds @ 2011-04-27  4:30 UTC (permalink / raw)
  To: Linux Kernel Mailing List

Another week, another keyboard destroyed by spilling coffee on it..
C'est la vie.

We have slightly fewer commits than in -rc4, which is good. At the
same time, I have to berate some people for merging some dubious
regression fixes. Sadly, the "people" I have to berate is me, because
-rc5 contains what technically _is_ a regression, but it's a
performance thing, and it's a bit scary. It's the patches from Andi
(with some editing by Eric) to make it possible to do the whole RCU
pathname walk even if you have SElinux enabled.

I've been alternately kicking myself for merging it, and just being so
pleased with the rcu pathname walk now extending outside of the
no-security confines ... I dunno. The patches are all pretty simple
(there's also a few dentry cleanup patches that were the result of me
looking at profiles and generated code), and it really is a rather
important performance thing, but at the same time I would shout at
others for trying to merge it to me this late. So I'll consider myself
properly chastised.

Other than that? We should have all the fallout from the block layer
plugging changes fixed now, and Tejun fixed the infinite CD-ROM
disk-change notification thing. So that's hopefully all good and done.

And then there are all the usual driver noise (including some hwmon
documentation), some ecryptfs and gfs2 updates and just various small
random fixups. The diffstat actually looks pretty good, most of it is
just one-liners and stuff like a few new device ID's etc.

Go forth and test,

                     Linus
