Generic 2-port PCI Express Serial Card - how to get recognized?

Hi folks;

I have a "generic" PCI Express "dumb" (16550 allegedly) serial card that
goes in a PCI Express slot.

FreeBSD doesn't see it, which I assume has to do with the card's "vendor ID"
not being in the table that FreeBSD reocognizes.

How do I get the ID from the probe (and/or probe the bus when the machine is
running?) - I assume I could add the vendor ID to the sio_pci.c module 
and it MIGHT work, yes?

It doesn't have a specific brand and documentation is basically "zilch"; I
figured it might work right out of the box, but so far, no joy.

Thanks in advance!
