Module dpms 

DPMS (Display Power Management Signaling) for x86_64.

Controls display power states via VGA register manipulation. Supports DPMS states: On, Standby, Suspend, Off. Includes an idle timer that transitions the display to lower power states after configurable inactivity periods.

When DPMS is Off, framebuffer blits should be skipped to save CPU/bus bandwidth.
