I have vesa patch and no dpms patch. backlight is not off in suspend.
The DPMS patch works ago, but it does not work for a few months.
It is said that you can use xset dpms force off to turn off backlight,
but i never tried that.

no other modifications, hw.acpi.reset_video is 0, but 1 also works
for me.
