up to 2.6.38, the iwl4965 driver was able to use power saving features
by invoking "iwconfig <interface> power on", at least when unsetting
the broken_powersave variable.

2.6.39 introduced a new iwlegacy driver for iwl4965 hardware, which was
missing power saving.  I was able to port the 2.6.38 driver up to
kernel 3.1, but it got too complicated for me with 3.2. 

Are there any plans to fix this power usage regression at some point in
the iwlegacy driver? I think there are still a lot of iwl4965 users out
there.

Yes, adding PS support is on my iwlegacy TODO list.

Thanks, I'd be glad if I could help, testing etc.

Hi Stanislaw,

is there any progress regarding this? If not, I could try to implement
it in the current kernel.  However, I don't have any knowlegde about
hardware related features.  If you have, maybe I could use your
knowledge to do it myself.

Regards,
Tino
