WPA-PSK problem on ARM

I recently read a couple of posts about possible endian-ness issues with 
the WPA support on ARM. I've also come across a problem with WPA on ARM, 
although I'm not sure if it's related...

I've just tried wpa_supplicant 0.2.4 and the 0.2.5 beta on an Ipaq 
that's running a derivative of the latest handhelds.org 
2.4.19-rmk6-pxa1-hh37 kernel, although I've dragged a lot of 
2.4.26-and-beyond network and wireless card driver code into the tree. 
While the hostap-driver works with an unencrypted base station, I 
couldn't get wpa_supplicant to connect to a WPA-PSK base station. When I 
rebuilt everything on an x86 box it connected fine. I was using a D-link 
DWL-650 with station firmware 1.7.1.

During scanning wpa_supplicant decides to skip my AP, like this:

Received 262 bytes of scan results (1 BSSes)
Scan results: 1
Selecting BSS from priority group 0
0: 00:11:92:a1:92:a0 ssid='8021xtst' wpa_ie_len=0 rsn_ie_len=0
   skip - no WPA/RSN IE
No suitable AP found.
Setting scan request: 5 sec 0 usec

... despite the fact that iwlist (from wireless_tools.27) shows a wpa_ie:

~/testing # iwlist wlan0 scan
          Cell 02 - Address: 00:11:92:A1:92:A0
                    Encryption key:on

Does anyone have any ideas about what might be going wrong? (I've 
attached more complete logs below). Or where I should start digging in 
the source code?

(Aside: I'm intending to move to WPA2 with EAP and AES when I can find a 
commercial base station that supports them... is the above problem 
likely to reappear then?)
