how do I tell my PCMCIA wifi card on iBook G3 800MHz

I can use wireless with wireless-tools fine, with no configuration at
all (no configuration: I don't even need to add a single line to
/etc/conf.d/net in order to use it).

However wireless-tools doesn't support WPA which I sometimes use. I have
installed wpa_supplicants but having read the WPA need user specify
which driver to use for it.

In order to know which driver to use I first need to know what hardware
I have. However lspci does not list my wifi device (nor lsusb). But the
devices does exist because I can surf the Internet with it.

Where do I start from here?
