2008/757 SPARC support for AST graphics

[Sherry Moore]

quiesce(9E) is a newly (since build 100) added dev_ops entry point
    http://docs.sun.com/app/docs/doc/819-2255/quiesce-9e?l=en&a=view

The Fast Reboot team would like the SPARC AST project team to state
in the final case material

    1. that quiesce(9E) will not be implemented at initial integration
       and why.

    2. their commitment to implement quiesce(9E) when SPARC Fast Reboot
       project is in progress.

Thanks,
Sherry
