Well, I've got one in my 9500 running (ahem)2.1:

puc0 at pci0 dev 14 function 0: Lava Computers 2SP-PCI parallel port (lpt)
lpt0 at puc0 port 0: interrupting at irq 24
puc1 at pci0 dev 14 function 1: Lava Computers dual serial port (com, com)
com0 at puc1 port 0: interrupting at irq 24
com0: ns16550a, working fifo
com1 at puc1 port 1: interrupting at irq 24
com1: ns16550a, working fifo

As I recall, the serial side of it just worked -- I don't think I've 
ever tried the parallel side.
