Public bug reported:

[Ubuntu 10.04 LTS kernel through upstream kernel version 2.6.34-rc6]

Kernel boot param "acpi_backlight=video" does not enable backlight
support as intended.  Setting it actually ends up enabling the video
output switching feature (the same as "acpi_display_output=video" does).

It is not possible to force backlight support, since no code ever
enables ACPI_VIDEO_BACKLIGHT_FORCE_VIDEO.
