The only way to do this without modifying the code is use a video card that doesn't support DRM. :) Let's first try to get your video to work with DRM. It seems the vsync methods, DRM or OpenGL, which use the hardware retrace to reach the next trigger has issues. I've attached a new patch for you to try out.

Yes, I'll probably create a ticket in the next day or two.

Please let us know if the new patch helps at all when using DRM or OpenGL vsync.
