Ok, sure. Thanks for the quick reply! I've had a look around at the current produce lineup, and it seems that nuc900 (w90x900) is still marketed, and as you say is similar to the n329 series. There has been one attempt to do a modern port for n329 in 2014 but it never got submitted. See http://comments.gmane.org/gmane.linux.kernel.kernelnewbies/49077 and https://github.com/mpthompson/linux/tree/n329 The code looks rather nice, so it's a pity that the effort stalled, but it should not be hard for anyone to start out with Mike's tree and forward-port it to 4.5.
