You might have more luck getting the puc driver to work with this card.
It is more flexable and meant for these kind of cards.
You will still need to figure out how the serial ports are organised on
the card though. Things like, does each serial port have its own BAR, or
are both inside one BAR and what the offset is where the ports start.
You might be able to figure that out from the linux patch though.
Once you figure those things out, you just add it to pucdata.c, build
a kernel with the puc device and off you go. :-)
