└─>Workaround broken graphics drivers (going away soon)
In linux kernel since version 2.6.31 (release Date: 2009-09-09)  
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.
