Sure, acpi_video.ko works well on a Dell Latitude D600, but it won't
work in parallel to radeon.ko. Both hook up to the same
kernel-interfaces (as i understood it hopefully right).
The module that has been loaded first wins the race and the other one
will load silently, but will not present functionality at all.
I think this has been on the current list a few times in the past it it
was said that it won't be trivial to fix.
Personally i prefer having direct-rendering support. So i only load
radeon.ko and acpi_video.ko stays on it shelf...
