Have you seen Alex Williamson's patch to fill out the /sys/firmware/acpi tree? http://marc.theaimsgroup.com/?l=linux-kernel&m8239031314885&w=2 -- "Next the statesmen will invent cheap lies, putting the blame upon the nation that is attacked, and every man will be glad of those conscience-soothing falsities, and will diligently study them, and refuse to examine any refutations of them; and thus he will by and by convince himself that the war is just, and will thank God for the better sleep he enjoys after this process of grotesque self-deception." -- Mark Twain
