I'm not sure if this is related, but I had same kind of problem with my Thinkpad T40p (with FireGL 9000 - basically same as Radeon) - after waking from hibernation laptop froze with these narrow vertical bands on screen.
I was using the default "ati" driver then, but waking from hibernation seems to be working now, after I switched to "fglrx" driver.
