First, you need John Baldwin's patch to /sys/dev/acpica/acpi_video.c to support DPMS. http://www.FreeBSD.org/~jhb/patches/acpi_video_dpms.patch It will be off by one line against current. The problem is that it will not cause xset to work. It will turn off the display when you suspend (S3). I think that we need a proper way to call this from vidcontrol or acpiconf as well as the proper patches to xset to make it all work. -- R.
