I have exactly the same laptop - HP Elitebook 8560w with a nVidia Quadro 1000M,
NVC1 (GF108) in nouveau slang - and used to suffer from similar issue.
But I've just tried Fedora 20 image for Graphics test

In the larger sense of "are you having a problem", yes there is a bug

But IMO it's not in the nouveau driver. Perhaps discuss this with the person on
the other bug who suggested there was an issue

Sorry, with acpi_backlight=vendor, I have /sys/class/backlight/nv_backlight/
folder (in place of /sys/class/backlight/acpi_video0/) and write in
/sys/class/backlight/nv_backlight/brightness

I think we're not understanding each other... you filed this bug because
nouveau wasn't registering a backlight interface. I pointed out why this was
and told you how to make it register one

With default option, after boot :
[root at DiNozzo ~]# cat /sys/class/backlight/acpi_video0/brightness

Same conditions, after pressure of FN down brightness key :
[root at DiNozzo ~]# cat

OK, but does the provided driver effectively control backlight? (i.e. writing
into /sys/class/backlight/...)

Yes :
[root at DiNozzo ~]# dmesg | grep backlight
[ 11.400712] nouveau [ DRM] ACPI backlight interface available, not
registering our own
But, if I use the option :
