After installing Snow Leopard with Airport Card (Turned Off) I noticed the Airport Card will not turn on any more.
This is an issue that has to be reported to Apple.
Repeat
DO NOT INSTALL LEOPARD WITH AIRPORT CARD TURNED OFF.
For what it's worth, I most likely had Airport off when I installed Snow Leopard and I have been having a heap of problems with my wireless connections.
However, now my MacBook says the Airport card doesn't exist.
I have a similar problem, but from the other direction. I installed SnowLeopard with airport on. Now I can't turn it off when I want to. I occasionally like to turn off airport, but since I installed snowleopard it does not respond when I click "off"
This happened to me the other day with my Bluetooth. Worked fine the night before, and then it just decided to stop working, and not make it self known to the OS. After a PRAM reset, everything was back to normal.
