	Ok, though have you got to the bottom of your flicker issues yet? I'm not 
seeing them on my kernel but of course it could be the combination of X driver 
etc that is causing it for you - but what I don't want to do is update the 
kernel with that commit and find that the flickering problem happens :(.

	I guess that the question has to be whether the problem you have happened 
before the fix for resume - if so then I'm probably fairly safe updating, but 
if not then I probably shouldn't....

Adam.
