8250_pnp                8096  0
8250_pci               18848  0

pps_core                9096  2 8250

these modules get automatically loaded.

Please note: the motherboard has 2 onboard serial ports. On the second
(which I can access via /dev/ttyS1 with minicom) is the GPS connected.
But there's also a plug-in pci board with 2 serial ports on it in the
system. Maybe that screws things up?
