I've blacklisted the video module and the screen does not noticeably dim
on boot. However, the Fn key controls no longer work and nor does
display dimming on battery power. I get better functionality with the
video module loaded, despite the reported problem above. The Thinkpad
fixes don't work for
Maybe you can temporarily blacklist the acpi video module. It is called
