KDM, buggy drivers and restarting X on logout

On IRC we had a discussion about buggy graphics drivers [1], which 
include an issue with the nvidia blob [2] and the open source ati driver 

A workaround for those is telling KDM to not reset the current X session 
but telling it to actually restart X by setting
in kdmrc.

<yofel> ossi: so the only difference between that being off and on is 
that logout is slower? (And you don't notice driver bugs)
<ossi> yofel: basically, yes

On my eeePC I don't notice any slowdown, and on my thinkpad shutting 
down plasma takes longer than restarting X. So do we want to eventually 
use that for precise if it results in a less-buggy-by-default release? 
And if yes, when should we enable that? Now, to get more regression 
testing, or later to have a longer testing phase for the drivers?
