For the time being, build an unprivileged version of xenolinux to
use in domains other than 0 (i.e. no drivers). Look in the
defconfigs directory to find such a config.

The problem is that some of the drivers that are built into the
dom0 version of xenolinux try using inb/outb to probe their
hardware. If the domain has insufficient privileged this
generates a GPF, causing the domain to commit suicide. Keir is
planing on adding a GPF handler that spots failing inb/outb and
returns 'ff', causing the probe to fail.
