Unfortunately, that's a mistaken assumption.
You must go through a carrier that supports BlackBerry because they need to provide you with a BIS account with a @blackberry.net email address. Without this, the BlackBerry refuses to even connect to the data network.
Essentially, you can roam on non-BlackBerry GPRS carriers -- only through a different carrier that supports BlackBerry.
Orange France uses a different system, the fact that the Dominician Republic APN ends in ".do" tells me that it's essentially behaving like a totally separate carrier from Orange France. That would be your important clue that you are out of luck and must switch carriers if you still want to keep using your BlackBerry.
