A question: Is the suspend function flaky? Does it work sometimes or do you never get a successful return to our system?
Since the pci=nomsi kernel parameter doesn't work, I'd suggest removing it and retrying a suspend again. This time, after the suspend attempt, post back the pm-suspend.log file again and indicate at what time you attempted the suspend.
You may be suffering from this - a successful suspend/resume but a blank screen.
