I think she'll be fine. Many kindergarteners need to move a lot and are pretty impulsive. There were a few very quiet well-behaved children (mostly girls) in my DS's kindergarten, but they were the minority. The key was that there was a teacher who knew how to contain and even productively harness that need to move. Ideally, the classroom will be set up in such a way that your DD will fit right in. If she doesn't it is probably more because of the teacher' skills than your DD.
