The express AirTunes does not require 802.11G (extreme) hardware, it will work with either 802.11 client (b or g). Though, oddly enough, I had a similar problem - both my iBook and G4/AGP seemed to lose connection with my Express (didn't show on the Airport config utility or as iTunes speaker selection). I plugged out the Express and then just plugged it back in and it managed to show up just fine again on both machines.
