got around to give 2.6.30* more testing. LED now works nicely but that is about the
only thing that works.

Tried computers linked in Ad-Hoc mode with WEP. 2.6.30 and 2.6.31.1 work nicely
on the other end.

On the ath5k end it seems like 2.6.31 choked after resume from suspend or when interface 
was reconfigured. 

2.6.31.1 does not work at all on this netbook. LED indicates activity but network does
not get associated. "iwlist scan" does display available networks.

After having tried 2.6.31.1 I have to cold-boot 2.6.30.x to get the ath5k working again,
simple reboot does not do it.

has that been merged into 2.6.31* ? 

The /sys/.../rfkill files are there but could not figure out anything that changes 
when hitting the hotkey.

Besides, I would think the LED will indicate rfkill status?
