I have the same problems on my Ubuntu 64 bit Hardy 8.04 Lenovo Ideapad Y510 59012891 R intel T5550 1.83Ghz CPU, intel x3100 GPU... My laptop my suspend did work until a update I had like a week ago. My screen fully dims on shutdown and startup AND when VLC media player starts and Dims when games start i.e. Glest, Warzone 2100.... This is a vary in your face problem.
