Sounds like Marcus' config will use the ACPI /sys/class/backlight interface by default. I think this is a good thing, since it's the preferred method on thinkpads. However, existing ACPI video drivers don't provide a nice, sequential set of backlight values, so it's easy to get "stuck" at a given backlight level if you just try to use the up/down controls. See the lkml discussion with the subject "[PATCH] Rationalise ACPI backlight implementation" for details on that, it may be that the patch in that thread will work for Marcus.
