No related.  Please attach your xorg log and dmesg output.

Booting in EFI mode I have had this problem occur on an iMac8,1. It also resumes with a white tint on the screen. I have not found a way to get rid of the white tint except rebooting.

Booting in BIOS compatibility mode does not exhibit this issue, the graphics resume from suspend properly.

I tested this with the 4.2.0 kernel. I have not tried other versions and do not know if this is a regression.

I would be happy to test patches, provide debug information, or other additional testing if it would be helpful.

I have seen a similar problem on an iMac7,1 and can test on it as well.

I am unsure of a good place to dig around to get closer to a solution on this.

Using the compatibility mode is your best bet.  Apple kind of does their own thing with respect to EFI.
