Help: Unable to WPS a Dell D610/Ubuntu laptop using wpa_supplicant v0.6 and v0.7

(Update: I tried wpa_supplicant v0.7, and saw the same problem)

WPS Enrollee: Dell D610, running Ubuntu 9.04; 802.11 driver: ipw2200; my wpa_supplicant.conf is attached
AP/Registrar: Netgear WNDR3700; configured  with WPA2-PSK and  allowing WPS-PIN and  WPS-PBC; SSID: vkrugNETGEAR-2.4G


I am  at a loss: is WPS even possible with wps_supplicant and ipw2200 on the Dell Latitude D610 laptop running Ubuntu 9.04 Linux?.

To  debug, I captured the traffic between the AP and  my D610 using OmniPeek.  I verified that the  AP 
was sending what appears to be the appropriate WPS IE in its probe responses (see the attached 
WPS-PIN-probe_req_resp_packets.txt); however, the probe requests from the D610/wpa_supplicant did NOT 
contain any WPS IE at all, even though wpa_supplicant log claims that WPS IE is being generated:
