Do all (or some) wireless cards available with laptops support PCF. Most of the APs don't support PCF. Is the situation same with client wireless cards.
I have never seen PCF mode implemented, but it's my GUESS that most client cards support PCF mode functionality. The AP has to let the client devices in the BSS know that it supports PCF mode before they will opt into polling.
