Bug#729765: I confirm the bug too

[Marios Sioutis]

Indeed, 13.11~betav6-1 fglrx-modules-dkms does not compile, but it seems 
possible to work around it if we recompile the kernel ourselves with 
iommu_intel or iommu_amd flags. Is there a possible fix for this for the 
stock kernels?

I can confirm the offending line being the following:
/var/lib/dkms/fglrx/13.11~betav6/build/kcl_iommu.c:191:28: error: 
'struct dev_archdata' has no member named 'iommu'
     if ( pdev->dev.archdata.iommu )
