Sorry, I'll try to clarify. My problems were: 1. since at least late March, I've had visual artifacts on resume that make the screen unusable; 2. more recently, the machine didn't resume at all. Applying your patch, I can successfully suspend to S3 and resume again, so problem #2 is resolved. This leaves me in a better position to try and test solutions for problem #1 (which might be an issue related to the Mar 13 firmware update on drm-next rather than a -CURRENT problem).
