I've added the above sysctl in -current and will MFC soon.  The goal is
to make it easier to test driver suspend/resume methods without doing
the whole system suspend/resume process.  If your drivers are working
right, you should be able to set the sysctl and run your system normally
while doing acpiconf -s3 (or 4) in a loop.

Please test and report any driver bugs found to the list.  Since acpi is
not involved at this point, bugs found should not be acpi bugs.
