I downloaded and installed FC4 for the i386 architecture, and found out that everything worked fine (as far as I could see!), with the exception of the built in wireless card.
The hardware is:
Broadcom 802.11g Network Adapter
SIS 900-Based Fast Ethernet Adapter
The laptop has a built in button, which is not part of the keyboard, for turning the WiFi on. It is located on the front edge of the machine, and it lights up when connected, and flashes when not connected.
