I have confirmed that input is not a problem. I can sleep and resume and then ssh into my laptop and do a 'cat /dev/input/mice'. Moving my finger on the touchpad generates output. Same for typing on the keyboard and doing a 'cat /dev/input/event0'. Now the question is: if my display wakes up--i.e. the backlight comes on and the contents on the screen right before suspend are displayed--do I have a video problem that I should be pursuing as such? Many of the ACPI video sleeping bugs on bugme.osdl.org have a completely dead display--i.e. no backlight.
