Zones give root access, but no kernel modules.  (A Usermode
OS would be fairly limited in what kernel modules it can use
as it likely excludes all device drivers).

You will need to completely rewrite the lower half of the kernel
(or remove it) as all supervisor code can only run in the
main kernel.

But before looking into a Usermode Solaris project, we can
also look at which problems we'd like to solve there.
(Is it generic upper-half kernel work, just filesystems, etc)
