From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>
i810_write_entry() is identical to i830_write_entry(), except the the
use of the AGP_DCACHE_MEMORY flag to signal that the PTE should be
encoded with I810_PTE_LOCAL. We want that on i830 if we have local
memory. So simply swap all gen2 machines over to i810_write_entry()
