I've created a driver that allows the screen to be shutdown by DPMS provided acpi supports video mode changes. Beware, this is my first kernel driver so it's nothing great. Hopefully it will help someone with enough knowledge build a better driver. It's a loadable kernel module and the only tweak required to get it compiling should be in the Makefile. You can grab it from: http://www.clearchain.com/people/benjsc/download/vesa_dpms.tar.gz A URL as the list strips attachments.
