Any sort of automatic suspend is simply impossible in a world where your 
drivers don't work properly. There's code for making intel and radeon 
handle suspend/resume themselves now, and nvidia before g80 should also 
be easy. More recent nvidia is going to be some work.

But yeah. Let's not have "Work around broken drivers" as a design goal. 
The argument against timeouts in wakelocks works just as well here.
