I bumped you, but:
Controlled Rage (Ex): When an urban barbarian rages, instead of making a normal rage she may apply a +4 morale bonus to her Strength, Dexterity, or Constitution. This bonus increases to +6 when she gains greater rage and +8 when she gains mighty rage. She may apply the full bonus to one ability score or may split the bonus between several scores in increments of +2. When using a controlled rage, an urban barbarian gains no bonus on Will saves, takes no penalties to AC, and can still use Intelligence-, Dexterity-, and Charisma-based skills. This ability otherwise follows the normal rules for rage.
It opens up skills,but doesn't remove this disclaimer:
While in rage, a barbarian cannot use any Charisma-, Dexterity-, or Intelligence-based skills (except Acrobatics, Fly, Intimidate, and Ride) or any ability that requires patience or concentration

Stilled or Silent spells still require concentration to cast, and as far as I'm aware a Quickened spell would still require a concentration check to cast while grappled (please correct me if I'm wrong) so I would assume that anything which requires a concentration check can be assumed to require concentration.
Since Supernatural Abilities are not spell-like, and don't provoke AoO or anything that would indicate otherwise, I would say as long as nothing in the particular ability indicates it requires concentration, it should be fine to activate while using a Controlled Rage (or even a normal one).
Even if you enter regular rage, I would think you could still hold the charge. Nothing in the description of charge-holding describes it as an activity requiring concentration. If you're struck by a weapon or spell or a DOT effect hurts you while you are holding a charge, it doesn't discharge.
