@Erno Kuusela -- I can confirm that the change suggested by your collegue does seem to fix the main resume issue without disabling the second CPU. At least that is what my testing seems to show on a Dell Studio 15 (1537).

I pulled the commit below back to the Intrepid kernel and I could suspend and resume without the workaround script. I should note that I have also confirmed that I get a hang always on the second resume with events/1, though it should be noted I am getting some kind of hand always on the second resume (with or without the patch):

    i915: Save/restore MCHBAR_RENDER_STANDBY on GM965/GM45

    This register is set by the 2D driver to prevent lockups, and so it needs to
    be preserved across suspend/resume too. This makes my X200s work.
