The *Intel* WiFi-NIC (Intel Corporation PRO/Wireless LAN 2100 3B Mini PCI Adapter) on my IBM Thinkpad X31 worked mostly out-of-the-box. I just needed to download the firmware and I was up. So did the SMC Ez Connect PCMCIA card I used on my previos laptop (I think it was a prism54 flavor), also once I snarfed the proper firmware for it.
I think the prism-variety you mention is what's used with the wifi-NIC on a desktop I have, that I wanted to run MythTV on but haven't had any luck with yet.
The firmware you mention, is that used with dkms or something like that?
I'm not sure what the firmware does exactly. Look in your /var/log/messages file. There will be some mention of 'failed to load firmware' associated with the driver load. You need to have a partitular file living in /lib/firmware/ -- the name is wired into the driver. The SMC Ez Connect card needed something called isl3890. I don't remember where I got this. My Intel card needed ipw2100-1.3*, this I got off a site after googling for 'firmware ipw2100' (or something like that). Getting the Intel was easy -- there is a web site with all of the info needed. Getting the prism firware was a bit of a hassle. You might have to unpack a file from the CD that came with the WiFi card -- this means you need some Windows tool to unpack/install it someplace and then copy the magic file from where the Windows installer/unpacker puts it to your Linux box and make sure it has the proper name. It is important to get the correct version for your card.
