[PATCH] drm/radeon/kms: Disable agp only if we are dealing with an AGP GPU

From: Jerome Glisse
Date: Mon Nov 30 2009 - 11:48:09 EST


On IGP if you pass option agpmode=-1 you would overwrite the set_page
function callback with improper function which endup in non functioning
hw. This patch will disable agp when giving agpmode=-1 parameter only
if we are dealing with an AGP GPU.
