After patching wpa_supplicant from 0.5.10 to 0.5.11, everything has worked well. Before, it would associate, yet DHCP would not work. Sam Leffler (sam@) has since committed it to CURRENT. I still have the original patch to RELENG_7[1] that the CURRENT patch was based upon. It is a bit old, yet I think it may still apply at least for the most part.
