So I've applied both patches on top of the 3.10-rc5 kernel.

Everything looks OK :
gfmichaud@dragonfly:~$ sudo rmmod ath9k
[sudo] password for gfmichaud:
gfmichaud@dragonfly:~$ sudo modprobe ath9k
gfmichaud@dragonfly:~$ dmesg | grep -i parameters
[ 289.311397] ath: phy0: ANI parameters: SI=3, ofdmWS=on FS=7 MRCcck=on listenTime=25 ofdmErrs=64 cckErrs=892
[ 297.359862] ath: phy1: Set parameters for CUS198

However, it looks like powersave is on by default (I've removed the item in /etc/pm/power.d that disabled it) :
gfmichaud@dragonfly:~$ iw dev wlan0 get power_save
Power save: on

Link quality seems to have improved a lot :
- in 3.8 without patches, "iw dev wlan0 link" shows me "signal" between -74 and -86 dBm
- in 3.10-rc5 with the patches, it shows me "signal" between -55 and -62 dBm

I'll do futher testing and report here.
