Nothing to worry about, just ACPI in BIOS is not implementing _BQC method with which you can query the initial brightness level of the display device. Frankly, I'm not getting any smarter from the commit message as to what it even got added for: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=98758faffc86ee6fe9504eeab75481ee7c1aa860 "kinda firmware bug"?? :-) Maybe Zhang/Len can shed more light on the matter.
