Add a module parameter to control the AGP aperture.  The AGP
aperture is an aperture in the GPU's internal address space
which provides direct non-paged access to the platform address
space.  This access is non-snooped so only uncached memory
can be accessed.

Add a knob so that we can toggle this for debugging.
