The agpgart layer handles this, so yes - XFree86 can directly transfer
image data through the AGP Gart window. Its not done as effectively as
it could be. The current case is
Xapp->sharedmemory->X->gart->Video Card
but unless things have changed XFree86 agpgart doesn't support remapping the
shared memory pages directly into the GART and referencing them.
