I'm sure someone is interested, although you might have slightly
better luck on linux-wireless@...r.kernel.org.

Also, I'm curious how you are running ath5k on 2.6.23.anything,
since the driver has not been merged upstream even now.  Is this a
distro kernel?  Your own hacking?  Or...?  It might be helpful to
know the exact origins of the kernel in use.

Thanks,

John
