I agree the bus driver is being a little unreasonable but, try to work with her. My guess is he's most talkative in the afternoon so maybe you could put together a "find it" sheet. This would be things he is to look for while on the bus: a blue car, a cat, a yellow house, a red flower, a dog...etc. Does he like to look at books? Maybe everyday put two different books in his bag. Or, a travel etch-a scetch. One of those drawing pads with a water pen. Put something different everyday. If it's her first year driving - she will be thankful for a kid that tells stories vs. screaming among other kids.. when she looks back. Haha.
