I have an old sawtooth with a GeForce 5200 256MB agp card installed
(pins taped) which would not boot except in safe mode. The 5200 is CoreImage
and QuartzExtreme capable but these features are disabled in safe mode
resulting in some strange artifacts and banding in Safari on some web flash
content. I cured the boot problem, restoring both features and the screen
problems in Safari disappeared. Your problem may be that your card does not
support CoreImage. System Profiler under graphics/displays will show whether
CI - and Quartz - is supported. I think the minimum card required is agp
(not pci) Geforce 5200 or later - or for ATI cards Radeon 9500 or later.
