I have an Atheros AR5008 (AR5416 / AR2133 chipset) mini-pci (32 bit) wifi card. If I boot into Fedora, with any of the kernels I mention in the kernel version area, I see this output during boot, and even after boot (while logged in to the main console as root). So, the wlan0 device is never available. Ath9k driver is loaded. But no device. So, what I do in order to fix the problem is to boot into windows (xp), bring up the card, and reboot into linux, and then the card works. This has been going on for several days now, and I have no idea what might be causing this. If you need more data, please let me know.
Hmm, perhaps you could try pcie_aspm=off kernel boot parameter.
