xorg DPMS weirdness with laptop

[Markie]

I had to patch the trident driver which does the whole turn off backlight
thing for the CyberBlade (which is what my laptop, unfortuantly, has) and
this works with xset dpms force off/suspend/standby. However, if I just
leave it alone it's still doing it's old behavior of making the screen
black but leaving the backlight on.

Any ideas as to why this might be? I have Options "DPMS" in my xorg.conf...
maybe i'm forgetting something stupidly simple :-) No doubt the case.

Thanks
