Subject: Re: [PATCH] Platform: add Samsung Laptop platform driver

Hi Matthew,

concering the hp-wmi driver I would like to answer a few questions.

My GNU/Linux Debian system with a self compiled custom kernel 2.6.37.3 is
running on a HP Pavilion DV7-4151sg notebook (dmidecode output, DSDT, and kernel
config attached).
I activated the driver on my HP notebook in order to achieve several goals:
(1) make the rfkill hardware button work
    (seems to work according to the output of rfkill list and acpi_listen)
(2) make the buttons for lowering and increasing display brightness work
    (do not work, no output with acpi_listen)
(3) the display back side has an illuminated "hp" logo which I would like to
    be able to switch off (alone or together with the display) to save a
    little energy
How can I found out if these functionality is achievable via ACPI WMI functions
or somehow else?
What would I have to change in hp-wmi.c?

Any help is appreciated.
Best regards,
Jörg-Volker.
