Some interesting behaviour there, thanks for reporting. I can't seem to
find anything related to HP backlight in acpi-support in Ubuntu either,
so I'm wondering what controls the backlight in Ubuntu. Perhaps Debian
does something that intercepts signals that are normally intercepted by
the BIOS or something. I have no clue, and no means of debugging this
either, so we'll have to work around it.
Please do the following two things:
(1) Run "acpi_listen" and then press these keys, and tell me what this
shows?
(2) Check out if you can control your laptop's brightness using some
kind of command. If I understand it correctly, the dv6000t has nVidia
GeForce Go 7400 video, which nvclock doesn't support. Try using the
"smartdimmer" tool. And are there files in /sys/class/backlight?
If you can provide me with a command (2) and a set of key values (1), I
might be able to get acpi-support to do this for you.
Hi Bart,
I tried `acpi_listen' and don't gives me any kind of return, I checked
the logs (/var/log/messages and /var/log/acpid) and I can't see
anything... I tried as well with `smartdimmer' and according to
`smartdimmer' he's changing bright but I don't see any difference even
making a change from `0' to `21' in the level.
`/sys/class/backlight' is empty.
In that case I don't really know how I can fix this up in acpi-support.
I can't detect the keys and I can't change the brightness. Check these
links:

https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/80512
Both of these unfortunately provide no solution other than "upgrade to
the latest Ubuntu version". But there was a good question there: if you
stop the X server, do the keys work? (If so, then it's a video driver
problem.)
Cheers,
Bart
