That big chip on the right is a PCI 4-channel serial port chip. In Linux 
they will show up as ttyS[4-7] (or ttyS[2-5], depending on your kernel 
version).

Actually there's a manual on the commell website, which states "Three 
16C950 High performance UART channels, first channel for GPS".

So you get a GPS on a real serial port, and two extra serial ports for free.
