Alright, like I mentioned earlier hibernate issues generally tend to be kernel bugs, I'll go ahead and refile. I don't have further tips for debugging; you could try turning on drm debugging (install xdiagnose, it's the first checkbox; reboot for it to take effect and then collect 'dmesg'), which potentially might reveal something of interest. Hopefully the kernel guys can give you further guidance here.
