Yes, it's me just, errm, rolling <cough cough> along.
Ahhh, NetworkManager. And you folks wonder why I don't use it. Although to be fair, it might have been Gnome, or the fact that it's Alpha, etc. etc. However, if I put Fedora on (I bought the 8 GB version--logic is that it will be obsolete in months, so I went for the very cheapest) I will probably simply use wpa_supplicant and scripts.
This is what happens with the ath5k module from 2.6.27. (Tested with Fedora's, Ubuntu's and a vanilla kernel.)
Start wpa_supplicant and get an OK. Then, one gets one of those ioctl errors, which at first, made me think it didn't really recognize the card. However, despite that error, the card works perfectly.
On the down side, the two sysctl options seem to be gone from the 2.6.27 kernels, meaning you can't get the LED lights working. (I haven't researched if they've been replaced by other variables, dropped, or simply overlooked at the moment.)
Sooo, within a few months, most distributions will probably support the card out of the box.
