I can't say 100% for sure, but I would say most of the gates for the 200's @ ORD are walk- up with the "luggage cart" next to the plane- just place your bag on that and they load it. If the GA is vigilant enough, they will come around thru the gate area w/green tags to put on your carry-on as there is no way it will fit in a overhead. If the flight is light, you might convince them to let you take it on and stuff it under your seat.
