Hmm if the only problematic pins are 8-10 and the other dosn't really matter, wouldn't it be easyer (or at least cheaper than a Hardwareprogrammer) to just add 3 Switches (or pull-down resistors like RuggedCircuits said) from some old hardware on this pins? Okay, softwareproblemsolving sounds more professional but ...finding switsches +soldering = 10 minutes, thinking about removing bootloader find and use hardwareprogrammer +install or change software >1 hour :
