I also had issues with my Acer, which would become unresponsive after hibernating. (Screen stayed black, constant HDD access, no reaction to keyboard input). Turning off hibernation, fixed that.
I'm also having a small issue with sleep occasionally. Upon wake-up the screen would just be a mess of horizontal lines. Putting it back to sleep and waking it up again always solved the issue (like in your case, daroga). Not sure whether that's the ATI drivers or something else.
