FPmommy, I totally agree about having an IQ that you can tell people so they don't just put you in the category of pushy parents who think their kids are gifted and roll their eyes.
It looks like we're going with another private school option for next year -- they seem much more wililng to work with us and provide some in-school options for acceleration and greater depth. This however means probably 2 1/2 to 3 hrs in the car for me per day. I have an idea of a possible driver to hire ... I'm going to try to be very persuasive and see if he would be willing to shuttle my son so I don't have to cut back on my hours at work!
