Hi Chris,
I tested today's compat-wireless - compat-wireless-2009-09-16.
Unfortunately, I still seem to have problems with the ath9k driver.
While pinging my wireless router - which is just next to where I'm sitting - I
consistently have 2 packets dropped after every 3 packets.
The details of compat-wireless tree:

--- openwrt.lan ping statistics ---
53 packets transmitted, 29 received, 45% packet loss, time 52212ms
rtt min/avg/max/mdev = 2.022/155.337/2028.724/450.597 ms, pipe 3
As can be seen from the icmp_seq nos., most of the times, I get 2 packets
dropped after every 3 packets.
And I'm running this entire exercise sitting right next to the router - which
is a Linksys WRT54GL running OpenWRT Kamikaze (8.09) release.
The rest of the setup on the laptop is plain standard Kubuntu setup - no
modifications done to any other file.
I'm including both ath9k-devel and linux-wireless mailing lists in Cc: -
maybe, someone from there might have a clue about what's going on.
