Take a look at the _pm code in current DRM CVS it uses sysdev to hook suspend/resume for DRM...

And to be honest this is "bollocks" I don't want to quote private mails here, but neither myself or benh said anything of the sort from my reading, we just a) didn't like your Xegl is the *ONLY* way forward approach and b) your approach stomped on any chance that older apps (and DirectFB) would continue working... we both stated we see a three-tier approach to merged drivers being the way forward, and I'm going to start adding hooks to CVS, just because we aren't willing to jump in and apply patches straight away might speak more about how we are "maintainers" and not "break everything in sighters to add a new feature.." You also have a whole world is a radeon or at least ATI approach, this doesn't help design the architecture, I agree with your goals but saying the whole world is against you one more time isn't helping this any.. also can you stop a)stating MS are going to beat us, nobody cares, Apple already beat us so what. b) the list of goals you have, everyone is very aware of them at this stage, its just most people also have other ideas that don't appear on your list and want to keep the options open..
