+         Current Graphics drivers tend to use physical address
+         for DMA and avoid using DMA APIs. Setting this config
+         option permits the IOMMU driver to set a unity map for
+         all the OS-visible memory. Hence the driver can continue
+         to use physical addresses for DMA, at least until this
+         option is removed in the 2.6.32 kernel.
