In How-To-Repeat, you said:
"Then associate a recent Windows Mobile 6.1 device to the FreeBSD box
running hostapd ..."

In Description, you said:
"The WM6.1 device recv ps-poll's for packets every 20 seconds ..."

AFAIK, STA sends ps-poll to AP; AP does not send ps-poll to STA.  Why
did your windows STA receive ps-poll from freebsd AP?  Did you capture
it by using 802.11 tap?

And which freebsd driver were you using?

Your problem looks like:
- Either freebsd AP did not properly configure TIM in beacons, which
could be easily found out by using 802.11 tap.  But I highly suspect
if you were using ath(4), TIM would be misconfigured.
- Or your windows STA didn't process TIM according to 802.11 standard.
