[PATCH] compat-2.6: enable ath9k

[Howard Chu <hyc@symas.com>]

This patch enables building the wireless-testing ath9k driver with the 
compat-wireless tarball at 
http://www.orbit-lab.org/kernel/compat-wireless-2.6/2008/08/compat-wireless-2008-08-06.tar.bz2

In addition to applying this patch, you must also copy the 
drivers/net/wireless/ath9k directory from the wireless-testing image into the 
compat-wireless tree. Just posting this for posterity since it seems that it 
won't be needed for much longer.
