    Well, I've been a mac user for only 3 years now, but I have just started to see my first Kernel Panic. Can anyone make sense of this?

    looking at the two lines above it looks like its your airport driver that caused the panic. startup in safe mode by holding shift when booting to clear the system caches. this may help the issue. if its a one off panic don worry about it. if it happens again ring Apple support. you may have a faulty Airport card. if the Airport card is fine try an archive and install to reinstall that driver.
