and a followup....

http://www.qbik.ch/usb/devices/devices.php is a list of USB devices that work with linux so far and http://www.qbik.ch/usb/devices/showdevcat.php?id=16 is the networking section.

Some of them were done long enough ago that the N800 kernel should support the driver, but it isn't clear how much work there would be to port it, would need to crossref with the other places on the site to see any ARM data.
