Hm, in that case it looks like your iommu works more like the gtt on intel
chips 

Don't overgeneralize there - on the GMA500/600 the GTT doesn't allow CPU
side access of the GTT map (ie you can't use it to linearise pages for
CPU view) and the 3600 is even stranger....

Sorry, I really try to totally ignore everything related to gma500 ;-)
