I'm trying to build a kernel with this Atheros AR9287 wifi card. I had it working last week and rebuilt the kernel without saving my config, now I'm kind of stuck.

The most immediate problem I see is that I have /proc/net/wireless, even though when I boot with SystemRescueCD it comes up fine.

Thanks in advance!  (Here's the info I have, feel free to query for more):
