I do have a USB mouse that won't work, usually reloading ehci_hcd does
the trick.

Security is indeed one problem I'm looking to resolve, because with
suspend, it goes back directly into the system, without having to enter

I wonder if there's some way to achieve something like winxp, which
resumes back into the login manager, not the usable system itself.
But that would probably require a session manager as well, I don't know.

Nonetheless, another bizarre "problem" (quote because it doesn't really
affect ordinary use) is that after resume, there're duplicate "basic
system process" (I don't know how to put these) possessed by root.

E.g. watch `ps -eF', there would be two instances of such processes as
