Why? Only driver can enable MTRR, as only driver knows region size
(there is one pending bug in matroxfb that it passes to MTRR
only detected memory region instead of full region available for
framebuffer; It causes troubles in 12MB configuration (which is
unsupported by matrox, but... it works). And driver can easily put
MTRR handle(s) into its specific area.
