jyoung posted a new version of AVRDude and a Bus Pirate firmware that speeds AVR programming up to 40x:
I’ve spent the past few days implementing some changes to the Bus Pirate firmware and also to avrdude to increase the verify speed performance. Since I don’t have an ATmega2560, I’m unable to write suitable code to be able to handle changing pages, so this code will only work with an AVR that has less than 64k memory words.
