Wrong, the readme says, and I quote:

"Rebellions no longer produce troops that require technology that the faction in
question does not possess. If the player
prefers the old style rebels this can be turned off with the command switch
-old_rebels."

It is not based upon the province, but upon the appropriate tech level. I also think it is era based - which explains why the Byzant poster above got a rebellion with Pronoi Allegion - you can get those in the Early Era so you can get rebellions with them. What you can't get is a rebellion in the early era in the HRE with Gothic Knights because they are a late era unit.
