I have ATI X1600 mobility too, radeon.new_pll=0 doesn't change anything for me, but I don't have any problems with my laptop screen, sometimes i can notice some pixels that look as if they were shifted left or right few centimeters, but it is rare. Real problems start when i try hooking up my external CRT monitor, it is wavy and unreadable(CRT display) while my laptop screen works as it used to. I tried switching to radeonhd driver, screen both on laptop and external monitor was not corrupted but it was terribly slow.
