Hwww well without getting into the reasons why you would choose a Jetway ... I generally prefer Asus and no probs w/ Gigabit either.
IMO the memory & PCI & N.bridges are pretty well supported. Most, not all disk interfaces are supported. Graphis is an issue (but you know what you have there) and on recent years the plethora of new network chips has caused come problems. Sound is dicey too. Check these out carefully.
This is a really good website, http://www.linux-tested.com/
but check the forums too. Search "www.google.comn/linux" for your specific board and read comments.
