A patch has been posted to linux-wireless which accomplishes the
workaround of disabling wireless power saving (ie. iw dev wlan0 set
power_save off) by disabling power saving in the ath9k driver itself.

I applied it to Debian's 3.2.41 kernel and verified that power saving is
indeed disabled (after disabling my on-boot shell script which
accomplished the same thing of course):
root@debian:~# iw dev wlan0 get power_save
Power save: off
