Please run "wpa_supplicant -c /etc/wpa_supplicant -ddd -i wlan0 2>&1 | tee log" and make sure devd isn't starting it for you (i.e., /etc/rc.conf should not have any ifconfig_wlan0 line).
Then please send me the "log". 

FWIW, I tested suspend and resume and I didn't have any problems. In version 0.7.3, it always required a "reassociate" but now it shouldn't be the case.
