I can't get it to work, too :(

ifup wlan0 results in

wlan0     Link encap:Ethernet  HWaddr 00:19:88:20:FA:20
           UP BROADCAST MULTICAST  MTU:1500  Metric:1

           TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
           collisions:0 txqueuelen:1000
           RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)

wlan0:avahi Link encap:Ethernet  HWaddr 00:19:88:20:FA:20
           inet addr:169.254.7.18  Bcast:169.254.255.255  Mask:255.255.0.0
           UP BROADCAST MULTICAST  MTU:1500  Metric:1

udhcpc fails with this, then.

iwconfig reports

wlan0     IEEE 802.11b/g  ESSID:""
           Mode:Managed  Frequency:2.412 GHz  Access Point: Not-Associated
           Bit Rate:0 kb/s   Tx-Power=16 dBm

And yes, I remember with older images I had it already working. 
Currently I'm using omap3-desktop-image-overo-200910121635
