I am using a custom boot img as well because of slightly better performance with better battery life but most of all because of the fast charge option.
So I have no idea if the supplied boot img will work, i guess you just have to try it yourself.
Just out of curiosity, which boot img are you using? I'm using Alex's 1.7.
