I would be somewhat surprised if hal itself would be preventing this,
but that's more of a question to madwifi list.

IEEE 802.11 does not support such a time measurement.. This is in TU and
what you are trying to do does not sound like something that would fit
well into IEEE 802.11..

I would say that you would be much more likely to get this working with
madwifi and Atheros hw that Host AP driver and Prism2/2.5.3 hw/fw.
