> Commit d7dc100374df0c21afd8a198336ecd7999697159, "Ath5k: unify resets"
> introduced a regression into 2.6.28 where the PCU registers are never
> initialized, due to ath5k_reset() always passing true for change_channel.
> We subsequently program a lot of these registers but several may start
> in an unknown state.
