Can you please tell us what you were able to test?  I'm curious about:
1) were you able to turn IEEE PS on and off?
2) were you able to use WPA2?
3) were you able to use WPA2 with IEEE PS at the same time?

(3) is really tricky and may need additional work.  One issue that I'm
seeing is that the driver gets out of sync with the device, the way
I'm reproducing this is:

1) use wpa_supplicant to associate to an AP with WPA2 security.
2) iwconfig eth1 power on -- you should see the LED blinking to
indicate IEEE PS (the LED is off while the device is sleeping)
3) issue a command or two to temporarily take the device out of IEEE
PS mode (ex: iwconfig with no arguments to look at the configuration
and stats)
4) the LED should be temporarily solid-on and then return to blinking
after the driver re-enables IEEE PS mode

Thanks again,

  -Andrey
