Does the device driver recognise the chip as a 16550?  It should print a
line such as "com1: fifo" during the kernel boot (accessible via `dmesg`).

The only thing that springs to mind is the name "urt16550a".  I seem to
recall some weird problem with NS16550A chips, and certainly all the 550s
I've ever used are NS16550AFs (note the "AF").

Sorry, that's all I have to offer.  Good luck.
