Is anyone using an Airport Extreme card with a non-Apple 802.11g router or access point? If so, how is it working for you. I just got an AE card today (before my iMac) and am surprised that Apple doesn't mention 802.11g at all. Stating it will ONLY work at highest speed with Airport Extreme. Hoping this is because at time of label printing no none else had 802.11g draft devices.
