That is a lot of bandwidth for an r2xx GPU to drive. Try only attaching one monitor. I suspect the memory controller cannot keep up with the requests for two large monitors and the 3D engine, and when you get underflow, you get the blinking. Does it work ok with only one monitor (xrandr --output VGA-0 --off)? How about a different mode? Try 1024x768 or 1280x800, etc. You can also try a different modeline for 1920x1080. try: Modeline "1920x1080R" 138.50 1920 1968 2000 2080 1080 1083 1088 1111 +hsync -vsync for example.
