Hmm, this isn't something I've been able to test.  One shot in the dark
would be adding -w to the wpa_supplicant command line in
/etc/rc.d/wpa_supplicant.  I know wpa_supplicant deals badly with
yanking and reinserting a nic under normal circumstances so I'm not too
suprised it's having trouble with suspend/resume.

I suspect wpa_supplicant is bringing it back up.  I'm not sure what the
answer is there.
