Not sure we even need it in stable that badly? It seems it only hurts
power consumption somewhat. And I just implemented waiting today too.

Although Bob has a point, we could change the way we pass the DTIM
period to the driver, only pass it in the powersave callbacks, and then
we could associate without it and just enable powersave only after
receiving a beacon. That assumes that drivers don't use it for anything
else though, of course, but I don't see anything else you could use it
for really.
