Yes, I can confirm this.

Without encryption everything worked pretty OK.

I only faced one very small hickup, but ath5k reconnected immediately again, so I don't think this is a real problem:

wlan1: authenticated
wlan1: associate with AP 00:50:18:3b:2b:04
wlan1: RX AssocResp from 00:50:18:3b:2b:04 (capab=0x461 status=0 aid=1)
wlan1: associated
wlan1: No ProbeResp from current AP 00:50:18:3b:2b:04 - assume out of range
wlan1: Initial auth_alg=0
wlan1: authenticate with AP 00:50:18:3b:2b:04
wlan1: RX authentication from 00:50:18:3b:2b:04 (alg=0 transaction=2 status=0)
wlan1: authenticated
