Doesn't change anything here. Display stays blank.
Sounds like your problem is separate from SSC then, more likely related to panel power or backlight control. Have you tried bisecting for the problem between 2.6.35 and 2.6.36?
Nevermind, I just checked out the bug, looks like it is panel power related. Can you try this patch?
Tried. Does not work.
If it doesn't work, can you send me the output of intel_reg_dumper from before you turn off the display and after you try to turn it back on?
See the links below (sorry, they files are a bit large):
