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. -- Nate
