I'm sorry but I think I'm a little far from you, I'm in Chile, so could be to expensive for me to send a card to you.
I tried now with a Linksys PCI WiFi card, and it works, I set up it in AP mode, but it doesnt work as AP, its visible, I can conect to it, it provides IP via DHCP, but no routing and is not possible to connect to PFsense BOX by this interface, this is the configuration:
<opt1><descr>WiFi</descr><if>ral0</if> <wireless><standard>11g</standard>
<mode>hostap</mode>
<protmode>off</protmode>
<ssid>PF</ssid>
<channel>1</channel>
<authmode><txpower>99</txpower>
<distance>- <wpa><macaddr_acl><auth_algs>1</auth_algs>
<wpa_mode>2</wpa_mode>
<wpa_key_mgmt>WPA-PSK</wpa_key_mgmt>
<wpa_pairwise>CCMP TKIP</wpa_pairwise>
<wpa_group_rekey>60</wpa_group_rekey>
<wpa_gmk_rekey>3600</wpa_gmk_rekey>
<passphrase>12345678</passphrase>
<ext_wpa_sw><enable></enable></ext_wpa_sw></macaddr_acl></wpa></distance></authmode></wireless>
<enable><spoofmac><ipaddr>172.27.101.1</ipaddr>
<subnet>24</subnet></spoofmac></enable></opt1>
