I like my built-in Intel ipw2200, supported out of the box. :-)
I have in front of me a cheap Edimax EW7108PCg (http://www.dabs.com/productview.aspx?Quicklinx=4MWH) PC card based on a Ralink chipset, which I used in the previous laptop. Experiment shows it to be supported out of the box on 2.6.22 using the mac80211/rt2x00/rt61pci module (provided appropriate firmware is present). Earlier kernels don't have this built in but it's available from rt2x00.serialmonkey.com (http://rt2x00.serialmonkey.com/).
When I got the card a couple of years ago I couldn't get WPA to work on the new rt2x00 driver but the "legacy" rt61 driver worked perfectly once I'd recompiled Fedora's kernel without the 4KSTACKS option. (It doesn't use wpa_supplicant but supports WPA-PSK via iwpriv settings.) It seems that things have improved since then.
