I've been trying to get the low profile version (part PEX2S553LP) of
this card to work in my system on and off for a while now.
Having added the following diff (which I keep meaning to submit in a
PR), I have the uart driver recognising the card.

However, I can't get a working tty on either serial port. When I
connect over the serial port, I have a blank tty, which clearly states
"Not a controlling terminal" when sent SIGINFO.

I'm currently trying to enable sio, but run into kernel compile time
problems already reported in
http://www.freebsd.org/cgi/query-pr.cgi?pr=166626 . Perhaps I need to
give up on sio and try using the puc driver with your patch
