Actually I didn't see when I looked before filing the report, but this looks like my exact situation including the suspend issues. Sorry for the duplicate report!
That bug is for a blank screen on resume not boot. Do you only get a blank screen on resume, but not boot? Also, is this a regression? I.e., did previous kernels work? If so, can you bisect?
