Well, we got a month out of the new experience before we hit the wall.

No, it did not come from anyone at school, it came from DD herself. DD had a meltdown in the parking lot of KFC almost 2 weeks ago now. The reason? "I'm overwhelmed with what I can do. 9 yr olds aren't supposed to be able to do all that I can. I wish I could give my friends my brain for a little while just so that they'd understand me."
When questioned about it I discovered that since she is now in 6th grade and not putting any more effort into her work (and still getting As) than before the big skip she is beginning to realize just how much smarter she is than most other kids. She was really thinking that she would finally be challenged and she isn't. She also is seeing other 6th graders who are struggling and she is having a hard time understanding how they are having such a hard time with stuff that she has known for a long time.
We will meet with the teachers next week and try and come up with some sort of a plan for her.
We knew this would happen, but we were hoping that it wasn't going to happen quite so quickly. It just really makes DH and I face the fact that we really do need to find other solutions for DD's education.
