v1 (FCC ID: TE7WN821NV1) at least identifies itself as:
ID 0cf3:9170 Atheros Communications, Inc. AR9170 802.11n

On this TL-WN821N v1 the one-stage (as published in binary from by Atheros,
so far I had problems with my self compiled one) and two-stage firmwares 
work equally well on a vanilla 2.6.31 kernel:
