I'm afraid the problem is in the way laptops cope with backlight management. Usualy the video chip is not the one signaling the backlight off but the bios deals with powermanagement. This is the reason why vbetool does work and DPMS from X.org doesn't, vbetool uses realmode but X.org isn't able to do this as it runs with the wrong permissions.
Please correct me if i'm wrong, this is just what my conclusion is from what i have seen. I do have the same problem on a savage chip in a Toshiba Satallite 4200 series.
