Power management: how to test it?

strange to say, it wasn' t my mistake....
I updated firmware (RAM download) to 1.7.4 and Power Management works.
It seems it's not implemented at all in 1.3.5 and 1.3.6
The "ping test" is valid and I can also see PS-Poll frames.
Only the "multicast" issue is still unresolved (there's a switch statement
in hostap_ioctl.c in which the options "all" and "unicast" are included
but there's no reference to "multicast"....I guess it' s the place where
is issued to the card)

I have problems in setting up power saving mode.
I do a:
iwconfig wlan0 power value X (X= 500m, 1, 2, 10 tried in sequence)
iwconfig wlan0 power timeout Y (Y=500m, 1, 2, 10)
iwconfig wlan0 power on
Making a iwconfig wlan0 now show
> the value X in the field "Power management".
The card is in managed mode and associated with the AP.
Now, I ping the (supposedly) sleeping station. An ethereal capture shows
that pings (ICMP echo request and replies) go forth and back, but no P
frames are sent, nor the "sleeping" station ever sets the Pwr Mgt bit in
the frame control. It's like power saving mode is not there.
I guess I made a mistake, but I don't know if in the setup or in the testing.
Is the "ping" a valid test t

could I do?
Another "strange" thing I got is that if I type:
iwconfig wlan0 power multicast (as "man iwconfig" says)
I get an error, something like "wrong parameter", while everything is ok
if I s
>ap "multicast" with "unicast" or "all". I guess that this is a problem
related to wireless extensions, but I am not sure at all.
