    I was finally able to get the ath9k drivers to work
under 2.6.26-rc1 by using the previous ath9k git patch,
the 16 new ath9k patches, the Berg's proposed skb->cb
patch and the following patch I constructed for ath9k
to mimic the skb->cb changes...

So far the ath9k driver seems to be working well with one oddity.
I find that the gnome menu applet (using the NetworkManager in Fedora 9)
shows a signal level of zero (even though it recognizes that the connection
exists to the wireless network). Is this a known issue?

ps Are all 16 patches now applied to the ath9k git?
