/*
- * Formal definition of the VESA spec:
- * On
- * This refers to the state of the display when it is in full operation
- * Stand-By
- * This defines an optional operating state of minimal power reduction with
- * the shortest recovery time
- * Suspend
- * This refers to a level of power management in which substantial power
- * reduction is achieved by the display. The display can have a longer
- * recovery time from this state than from the Stand-by state
- * Off
- * This indicates that the display is consuming the lowest level of power
- * and is non-operational. Recovery from this state may optionally require
- * the user to manually power on the monitor
- *
- * Now, the fbdev driver adds an additional state, (blank), where they
- * turn off the video (maybe by colormap tricks), but don't mess with the
- * video itself: think of it semantically between on and Stand-By.
- *
- * So here's what we should do in our fbdev blank routine:
- *
- * VESA_NO_BLANKING (mode 0) Video on, front/back light on
- * VESA_VSYNC_SUSPEND (mode 1) Video on, front/back light off
- * VESA_HSYNC_SUSPEND (mode 2) Video on, front/back light off
- * VESA_POWERDOWN (mode 3) Video off, front/back light off
- *
- * This will match the matrox implementation.
