I'm totally ignorant of the inner workings of suspend to ram and how
devices deal with it. How do I disable wakeup for the EHCI controllers?

Also, does wakeup have anything to do with suspend. As the name
suggests, it sounds like its more of a resume thing. But again, I'm
ignorant when it comes to these matters. I just want to point out that
without the script, the machine never makes it to a suspend state.

I wounder what windows does. Of course, vendors bend over backwards for
MS, so it may not need to do much, or MS does something completely
different. I do have this still as a dual boot with Windows7. I don't
wipe my boxes clean of windows anymore. If I have to pay the damn MS
tax, I might as well keep what I paid for :-p
