It looks like it's failing in the place the video probe should be.
What video mode do you boot in? Maybe see if changing the video mode
causes the symptom to change. Do all the modes work under Mac OS? If
you have bad video memory, it'll be obvious at the larger resolutions.

Also, the "ams" device is somewhat uncommon -- you could rule out that
driver by booting without the mouse, or with a different mouse.
