Well, both 802.11b and g work at the same frequency - 2.4 GHz so 802.11g
is backward compatible with 802.11b. I think 802.11g was drafted as an
extension to 802.11b. But 802.11a works at 5GHz so is not compatible
with 802.11g or 802.11b. 

I am not sure if you Aviator 2.4 PC card is g or a. A 802.11g pc card
will work with a 802.11b access point but the data rate will fall back
to 11Mbps. It will work the other way around too, a 802.11b pc card
with a 802.11g access point. 

802.11a would not be as popular as 802.11b/g but from what I have read
802.11a is better because of less RF-interference from other devices.
The 2.4GHz has a problem because other devices like cordless phones also
work at the same frequency.
