Nate:

 I managed to get these errors on bootup tonight:

Jun  4 22:28:07 notebook login: ROOT LOGIN (root) ON ttyv1
pci0: Failed to set ACPI power state D3 on (null): AE_BAD_PARAMETER
pci0: Failed to set ACPI power state D3 on (null): AE_BAD_PARAMETER

                          Kind regards,
                          Jonathan
