I even plugged in a USB keyboard, suspended, and tried to wake it up
with that. That did not work. I even enabled what you stated above, with
no effect (with keyboard or usb storage).

This suggests that the original version of the patch is superior.  
There's not point in saying the controller is wakeup-capable and trying 
to enable wakeup if it's not going to work.

I would point out that I have yet to get wakeup via usb to work with any
patch.

Maybe I missed a patch, which one is suppose to work?

No, I think it's more likely that USB wakeup simply can't be made to
work on your computer.  Whatever caused the original suspend problem
also interferes with wakeup.
