This one is a bit tricky, because the support needed for the wireless ethernet on the laptop is only available in development versions of the orinoco driver. It's stalled there, because the person who was developing it was killed in an automobile accident last year...
Anyway, the wireless card uses the "orinoco" chipset, interfaced to a USB controller in the laptop. This means it needs a special version of the driver; in addition, it works by downloading the firmware to the card when the driver is started.
So, to get this stuff to work:
tar xvzf orinogo.tgz cd orinoco make make install
/usr/lib/hotplug/firmware/orinoco_ezusb_fw
And, with any luck, it should work!
