From the GLoAQ:
If the Overlord plays RAGE on a Lieutenant during a battle action, how many attacks does he receive - 3 or 4?
Two, actually. "Rage" reads: "Play when you activate a monster. That monster may attack twice during this activation (four times if it has Quick Shot)."
A lieutenant who has declared a Battle action may attack twice during his activation. "Rage" has no further effect - it is essentially granting the lieutenant an ability it already has. A much stronger play is to declare a Run action and then play "Rage," which would allow the lieutenant to move twice his speed and attack twice.
Now the basic rules for Run say, that you get to move twice your speed and no attack.
Stun says, depending on the monster type, either move or attack (masters) or do nothing (normals).
This makes me think that it would be a legal move to play a Rage or Charge card on a stunned monster (at least on a master) and still make some attacks and/or movements, analoguous to the legal Lt. Run/Rage combination.
Stunned Master, Select Move, Play Rage -> Single movement , two attacks (four if Quickshot)
Stunned Master, Select Attack, Play Charge -> Double movement, One attack.
Stunned normal monster, Play Rage -> Still two attacks?
So basically, the Rage and Charge cards (and Enrage as well for that matter) would ignore Stun for a master monster (same outcome as played on an unstunned master), and make some actions possible even for a normal monster.
Opinions here?
