Retitling to be more precise and reopening.

Marwan, please open a new bug on bugzilla.kernel, product ACPI, component
Power-Video, and let us know the bug number so we can track it.  Be sure to
include:

 * full "dmesg" output from booting with and without acpi_backlight=vendor,
   as an attachment

 * full "acpidump" output, as an attachment

 * full "lspci -nnvvv" output, as an attachment

If you have a chance to try 3.8.y from experimental, that would be useful,
too.

We can coordinate further work on this upstream.

Thanks, and hope that helps,
Jonathan
