AIUI, it's primarily a matter of the machines for which libreboot support exists. So, for example, the X60 and its tablet version are supported, but the X61(t) (of which I have two in a box somewhere) aren't. This is a terrible bummer for me, because that's still one of my favorite machines I've ever owned.
