I have Fujitsu S6210, with same wireless card. I pretty much a newb too but i was able to get mine to work.
Download the driver from ipw2200.sf.net (u might need to download the firmware too). Unpack it:
# tar -zxvf ipw2200-0.11.tgz
and you will prolly need to use the patch, also found at SF.
i get an error when i type ./load but somehow it still loads (you can check with command iwconfig and you should see your ipw2200 loaded at eth1)
U might also need to configure it a bit with iwlist, iwconfig.
theres some steps that can be found at this link:
hope that helps
