AirPort Express and generic 802.11g

Apple’s new AirPort Express gadget is very cool (hey, maybe I’ll get one for Fathers’ Day.. hmm..) However, I can’t tell if it works with generic 802.11g base stations or only with AirPort Extreme units. I have a Linksys 802.11g station now and would prefer not to replace it just so I can use one of these.
