If you are running CURRENT, John Baldwin has added VESA DPMS to the acpi_video kernel module. I suspect that this will work on you system, but I am never positive of anything on any other laptop. google on acpi_video_dpms.patch in Google Groups. I don't know when this might be committed to CURRENT, let alone MFCed to STABLE. If your Dell really does not support DPMS, I'm not sure where to try. -- R.
