Older kernels won't have intel_iommu_found() even with your other patch, 
so this code is still needed.

We can't compile the external module on a 2.6.27 tree that has the iommu 
patched in; we can probably make this work by renaming 
intel_iommu_found() to kvm_intel_iommu_found() in hack-module.awk.
