I use a WGA600N with my TiBook. The power supply rating is almost exactly that what you would get from the FireWire port, so I fashioned a simple adaptor from the FireWire power pins to the WGA's power plug and a short Ethernet pigtail and velcroed it all to the lid. The WGA's configuration interface is also fully compatible with Classilla and iCab.
Sure, the TiBook has a PCMCIA card slot, but the antenna sticking out is just asking to get snapped off, and this gives me WPA2 access in Mac OS 9 since it's the WGA that's doing the wireless, not the machine.
I would think that the power draw for the Netgear would be less than the floppy at peak, but it would draw it all the time, so it's something to think about. Also, I don't know if the browser choices on a 520c would allow you to configure it (maybe iCab 2.9.9). You might have to create a custom app in something like FutureBASIC that could automate SSID selection.
