Yeah, they are working on it. Maybe some day it will have some results as well. I mean it's just enough to read LWN: there was an article about "sound in Linux - it's a mess" a couple of weeks ago. There are problems with graphics support (either no free software driver or the performance of the hardware is "modest"). Pretty much problems everywhere the user looks at. And these problems are not too recent either. So I can understand the companies in the embedded business if they fail to see the advantages of the free software model (except the price tag, which with the support costs might not be that good).
