ok, that's very bad :-( I fear we cannot do something about this now. I guess we have to wait for the ChromeOS people to catch up with the newest kernel api development, or some other "wonder"... If you really need reliable resume, just remove the binary blob and use the framebuffer driver. It is fast enough for most situtations.
