in that case my advice would be to try 3.6 FIRST, 

if it doesn't fit, optimize out what can be

if it still doesn't fit (and only then) should you try downgrading the kernel... 

but do it in that order, do not jump to ancient kernel if you can avoid it, maintaining aging kernel is hard and costly, you will be much better if you start your project with the newest kernel
