If you want faster suspend, that should be easy. You'll need *current* 2.6.16-git , and userland tools from suspend.sf.net . There's HOWTO that explains how to set it up.

Actually Rafael was *very* nice at him, I'd say. Pointing for tiny inefficiencies, without patch attached is not really helpful. I have repeatedly pointed him on ways how he can *really* help. There are ways to do suspend2 in userspace these days, but Nigel refuses to use them.
