The guest os code is polling this register on a very fast interval, and when it detects a certain # of scanlines have been counted, it will swap it's display buffers, ie, it's waiting for the vblank, so it can have nice smooth animations.
Since this is all custom, I'd rather raise an interrupt when the DAC reaches the final portion of the frame buffer... This has to be better than polling.
