What version are you running? 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!
