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.
