It *does* matter what the UART is reported as. All internal modems
(winmodems or not) use a "virtual" UART. There is simply no reason
to convert to serial and back to communicate with a card on the
computer bus. But it does matter that the UART reports itself as
an 8250 or 16550 because if it reports itself as an 8250 the OS
will think that there is no FIFO buffer present and performance
will suffer.
