Update to that earlier thread:
I have been running a patch below for a while and baud rate seems to
be correct on amd64 at least. I have tested my card against one
ARM development board and with custom max232 circuit using
xbee or usb-ftdi on the other side [1].
I think Stuart Henderson tried some similar diff, but couldn't get
it working properly.
(For a card with 8 uarts and different id, the diff needs to be
modified a little.)
