Yes, with the latest versions of the station firmware (1.7.x and newer).
See the current CVS snapshot for an example of how this can be done
(generic element RID). wpa_supplicant uses this to add WPA IE into
(Re)Assoc Request frames and hostapd uses this to add WPA IE into Beacon
and Probe Response frames.

That's not going to work correctly because Beacon frames have to include
exact timing information from the MAC and Prism2 firmware does not
provide way for sending your own Beacon frames with such information.
