Thanks, this definately answered some of my questions and confirmed
some of my understanding.

I'm still not clear on what work is ongoing in which
repositories...direct-io.hg, iommu.hg, or the main line.  I'm trying
to understand how these repositories map to the following features:
 - Neocleus
 - Support for hardware IOMMU, either AMD or Intel.

Is any of this stuff in the main repository (or, are patches for this
stuff relative to the main repository)?

Thanks.
