ok, after un-hacking frameworkd to re-enable auto-suspending and a clean
reboot I have the WSoD on resume. Before I had suspended the freerunner
via apm -s and it didn't resume at all (had to rip out the battery).

Something else I could try to debug? Is there some way to completely
reset the video when it is in WSoD state?
