Anyone come across this? My Airport Extreme card in my G4 ibook just randomly started causing kernel panics. I was uploading stuff to our ftp server and the laptop crashed, and ever since it just won't boot with the airport card in, it reaches the Apple/Unix Circle screen, then has the kernel panic screen. In single user, it has the lovely "kernel panic, we're holding here" message once I exit. Any way to get it working again, or is the card just scrap? EDIT: It boots fine without the card, though it has frozen once or twice (always during the boot, never in use).
