I personally cannot test 3.1 anymore but I can tell you that 5.4 does not
work out of the box as of Sunday night updates.
By the way, no need to remove 3.1 from the bug summary...

Bugs,
The patch removes MacBookPro3,1 from the list using the macbookpro
addon, which is good since the addon does not work for that machine, and
as stated, should be picked up by the nvidia backlight driver. But there
could be other reasons for the backlight not to work, could there not?
On a
The only other reason is that the kernel module is not autoloaded. Again
it's fixed in more recent kernels.

i don't know, i can just state that it is not fixed for my macbook pro
santa rosa (3.1). it worked for a day or two some days ago, but overall
it is broken and the only way to control backlight is to do it in the
console and then go back to X. same for all other function keys
(f3,...).

i just took a short look at ubuntuforums.org using intrepid and
backlight as search terms and there are many reports about the same
problem (and they are just some days old). hence, imo the bug is not
100% fixed yet.

loading mbp_nvidia_bl does not solve the problem in my case. to change

Perhaps you can try the new hald-addon-generic-backlight, which is
available in the latest HAL upstream. With it, one can configure an fdi

The current hal configuration is wrong. The culprit is the hald-addon-
macbookpro-backlight, which assumes the ATI graphics card, which MBP3,1
does not have. A similar problem exists for MBP4,1. The MBA1,1 is not
even listed.

As far as I am aware, for MacBook Pro 3,1 and 4,1, the mbp_nvidia_bl
module is what is needed to make the backlight usable. I have a 4,1, and

loaded.
I will have a dig in the hal package to see what has been c hanged.

A question regarding addon-macbookpro-backlight, from someone unfamiliar

Why is the macbookpro-backlight addon reading the chip directly, instead
of using the applesmc module?

Further reading of the fdi file for MacBook Pros, I see that machies
that are MacBookPro3,1 or earlier will still not work with the new
backlight functionality that I have working. The fdi file needs to be
rewritten to only add custom backlight keys for those MacBook pro
generations that need it,
3.1 has NVidia. I am pretty sure that the ATI chip prior to that
works...
