Caveat; ia64 is a different architecture, but it was on Intel VT-d
chipsets, which therefore supported the IOMMU API and ia64 maps guests
the same way.  This is the same problem I ran into trying to name the
vfio iommu driver for x86.  It's not really x86-specific, but it's got
to look and smell pretty similar.  Thanks,

Alex
