I think that Nate has added support for PCI power states to current and will probably be MFCing them soon. I have been testing them for about 2 weeks. You also want to use jhb's acpi_video_dpms patch if the back-light on your display does not turn off. This is a BIG power sink. I'll attach a copy that is clean against stable of yesterday (and probably today). Be sure that you load acpi_video! -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
