This is  a pretty poor choice for a PCI card, since serial ports
default to IRQ 4 (com1 & com3) and IRQ 3 (com2 and com4). Try some
other device

this is wrong, ttyS3 should use IRQ 3

If you didn't configure the pnp card, it probably took on some default 
values.  The safest thing to do is either remove the SB16 card, or get 
isapnptools, run the pnpdump program, and deactivate all the devices
(ACT N) in the /etc/isapnp.conf file.
