It disables using the page attribute table for cache control of memory
mappings, just using the (more coarse) MTRRs instead. For a more extensive
description see e.g. http://www.intel.com/Assets/PDF/manual/253668.pdf, chapter
11, though I imagine you'll find it fairly technical. I guess the fact that
nopat helps implies fglrx messing up cache control for some memory mapping,
e.g. for a buffer object for a texture resource or color buffer. I'm obviously
not familiar with fglrx internals though, so maybe I'm way off.
