STR is always working on my X60s. No green screen, no hang. Both s2ram
and "echo mem > /sys/power/state". It's STD that's having problem.

But strange thing is I could even restore console after STD even
without agp and i915 module loaded, so I don't know how the console
vga got saved and restored.
