Removing the atomizer's bridge is one way, and surprisingly simple.
Many have even been able to at least partially (if not fully) restore a seemingly dead atomizer by removing the bridge and wicking material.
Many have also posted methods to do this. Here's one I posted a few months ago: http://www.e-cigarette-forum.com/forum/polls/56499-510-atomizer-resurrection-mod.html
Hopefully you'll be able to bring a few back to life. Good luck!
