There is a patch which should take care about vendor specific and the generic
ACPI video backlight and display output switching.
It will still take a while until it will get mainline, etc., but I really would
appreciate if you can give it a test as soon as I can provide a kernel rpm to
test.
Just in case further digging is necessary, can you check whether you are
running the latest BIOS (there often are updates because it is a relativ new
Vista functionality to switch via generic ACPI backlight functions).
You may want to have a look at the BIOS README if provided and check for
backlight changes...
Please upload acpidump and dmidecode of the machine (if you intend to update
the BIOS, please do so after updating).
