Hi,

You may need to add a quirk to src/sys/dev/puc/pucdata.c and rebuild 
puc, to get the sio or uart drivers to attach correctly to the serial 
ports which are behind the bridge device on your PCI card.

Some cards have their serial ports at different bus offsets/addresses 
behind the bridge, or use different clock multipliers. See the Dell RAC 
UART entries at the end of the file for an example.

If NetBSD supports your card, then syncing up our pucdata with theirs 
may be the way to solve this.

Regards,
BMS
