Laptop screen not coming back on after closing and reopening lid.

I remember having this issue before but cannot seem to find the documentation that i used to fix this previously.

I have a Dell b120 with an intel 915 igp

When i shut the lid and reopen it, the screen remains blank.  If i recall, it was something i had to set in the power management.

Re: Laptop screen not coming back on after closing and reopening lid.

Upon upgrading to the 2.6.36 kernel, Lenovo S10-3 would not resume after suspend.

Adding 'intel_idle.max_cstate=0' to the kernel boot options makes it work.
Tried that because of: https://bugs.launchpad.net/bugs/634702

May work for other intel graphics cards as well.

Did the job for me on a Samsung NB30. Most excellent.
