Does FreeBSD support SB16C1058PCI RS-232 cards?

[dieterbsd at engineer.com]

I'm looking at the SYBA SD-PCI15029 8 port RS-232 PCI card
http://www.sybausa.com/productInfo.php?iid=994
$32.99 from newegg:

Chipset: SB16C1058PCI
Compatible with 16C550

But... grep doesn't find any reference to the SB16C1058PCI
much less SD-PCI15029.  I fear that 16C550 isn't enough?
