The 802.11g gumdrop ones (I think Snow was the official designator with Graphite being the 802.11b gumdrop) should be the same settings wise, though the config utility looks a bit different. And they do support WPA2, though depending on the age of the unit, it may need an upgraded firmware. 5.7 is the most recent release I can find, and it does have a note on that page about Windows users needing a hotfix for WPA 2 support (later rolled into XP SP3).
