RT2561/RT61 fail to connect to secure networks when powersaving is enabled

[Wouter Stomp]

There is a regression in 2.6.32 making these drivers fail to connect when powersaving is enabled.

Temporary fix: disabling powersaving:
sudo iwconfig wlan0 power off

There is a patch available upstream that disables powersaving on these cards by default.
