absolutely not. in the contrary case, even ripping them off the kernel
and integrating them into xen, e.g. in order to get rid for some of the
latencies involved by keeping front- and backends in separate address
spaces, would start to look like a viable alternative.
running drivers unmodified is a major design criterion, because
maintenance cost ist a fundamental part of the overall equation.
