No it's not enabled by default. So the 10s delay is rather weird! Is this a
property of any version of Xen on this machine (e.g., 3.1.0, 3.1.1)? Or is
it a new property of recent xen-unstable?

Oh dear. :-( For that kind of machine I tend to stick in a PCI serial card,
work out its BIOS-assigned resources, and then manually specify the I/O
ports and IRQ on the Xen command line. Working with no serial at all is way
too painful.
