There is Intersil firmware with PCF support, and linux-wlan-ng supports it 
if the necessary RIDs are present.  Look for "pcf settings ignored" in 

It should be possible to program the MAC from userspace to use PCF.  
However, HostAP doesn't seem to provide the interface for that.  It should
be possible to set and read every byte in every RID.  "iwpriv
set_rid_word" is insufficient because it's write only and affects only two
first bytes,
