I think the perform backend for oprofile is the right way to go. I'd even go further and say we should merge the perfom backend with oprofile as the only user first, because a) the current perfom user interface is a complete mess and can't be merged as-is and b) that ensures the oprofile backend works perfectly and we can kill some existing code in exchange.
