I wasn't able to boot kernels earlier than 3.6 on this Macbook Pro retina due to various issues, and it occurs on kernels between and including 3.6 and 3.7-rc3. As we see read being called, I've taken the lsof output [1]. Should the DPMS functions be deregistered prior the hardware being placed in D3, or is it more that the functions should check if the card was put into D3 and just return?
