There have been cases in the past when not all stable updates have been 
applied, so it might be a bit disingenuous to advertise a stable updates 
realese number. That being said, I'm still in favor since its going to 
be pretty close. Keeping track of the DRM release state is also gonna be 
a pain. Is the plan to watch for any .33 stable kernel updates that 
affect DRM and update the DRM version number accordingly, e.g. drm33.x ?
