From reading the original article, it seems that Linux can use the DSDT table handed to Vista, but that Foxconn's BIOS deliberately detects Linux, and hands it a broken DSDT table; I will wager that this behavior does violate the ACPI specifications, which Foxconn claims to honor. It's equivalent to having a web application that states that it is W3C-standards compliant, purchasing a subscription, and then discovering that it only works in IE, not because Firefox and Safari don't work with it, but because they've added a bit of browser-detection code that turns other browsers over to Tubgirl.
