On VT-d supporting platforms the GGTT is allocated in a stolen mem section separate from graphcis stolen mem. The GMCH register contains a bitfield specifying the size of that region. Docs suggest that this region can only be used for GGTT and PPGTT. Hence ensure that the PPGTT is disabled and use the complete area for the GGTT. Unfortunately the graphics core on G33/Pineview can't cope with really large GTTs and the BIOS usually enables the maximum of 512MB. So don't bother with maximizing the GTT on these platforms.
