I have a Targus branded Stowaway keyboard I got from some Asian seller on ebay. The packaging was generic, but the keyboard looks genuine. Not sure how close this is to a Fellows-branded one.
Last I remember, under pdaXii3, all the keys worked except the pipe/backslash key -- in fact that key wasn't even recognized using xev. The keyboard worked fine when plugged into a windows box, and all the keys were recognized when plugged into an ubuntu laptop (although there were key repeat issues in my quick look).
