Add it to your kernel. 2.4.22 has support so I'd imagine anything above has support. Slack 9.0 uses 2.4.22. If you want, you can use swaret to get the 2.6.# kernel. Most people report having to use linuxant drivers for wifi cards, but there are some cards that have native drivers. Check around proxim I think has native drivers, but I'm still using an 802.11b.
