Trident blank. This module turns the back-light off when the console 
is blanked on laptop computers that use Trident Cyberblade video 
controller.

To make the module, type make. You need to have the necessary headers 
and build system under /lib/modules/`uname -r`/build.

To activate, insmod trident_blank.ko.

To deactivate (and return to default behaviour of blanking the screen
but leaving the back-light on), rmmod trident_blank.
