I'm starting to get desperate trying to get my old D-Link card
working, which is why I embarked on a quest to compile the driver on
ArchLinux after unsuccessful ndiswrapper attempt.

Unfortunately, it just so happens that the card reports a completely
unambiguous radio ID, 0x02.

I don't suppose this firmware file even exists.

Here's relevant dmesg output:
