Ian's work generally works and runs now, it just needs drivers to be
ported as well.  libpciaccess is in git, and you want the pci-rework
branch of the server.  He sent a mail a while back about the work needed
to port drivers to it, which IIRC is basically just collapsing multiple
mappings into one, and fixing the Probe function.
